Checking into a hotel is a small grammar showcase: in three or four turns you use the polite conditional (Chciałbym — "I would like"), the duration phrase na + accusative (na trzy noce — "for three nights"), the numeral split that makes trzy noce but pięć nocy, and the reflexive verb zameldować się ("to check in"). Each is a high-frequency travel tool, and they cluster naturally in this one scene. Read the dialogue, then work through the breakdown.
The exchange is between a guest (Gość) and the receptionist (Recepcjonistka), in the polite pan/pani register throughout.

Grammar in this dialogue
The conditional for politeness — Chciałbym, Czy mógłby pan…?
The guest doesn't say Chcę się zameldować ("I want to check in") — that's grammatical but blunt. He says Chciałbym się zameldować ("I would like to check in"), and the receptionist mirrors the courtesy with Czy mógłby pan wypełnić…? ("Could you fill in…?"). This is the conditional used as a politeness softener, exactly like English would like / could you. It's built by adding the mobile particle -by plus a personal ending to the past-tense stem.
Chciałbym poprosić o fakturę.
I'd like to ask for an invoice.
Chciałabym zmienić pokój.
I'd like to change rooms. (said by a woman)
Czy mogłaby pani powtórzyć?
Could you repeat that, please? (to a woman)
Two points learners stumble on. First, the conditional is gendered: a man says chciałbym, a woman chciałabym; mógłby (he could) vs mogłaby (she could). Second, the -by particle is mobile — here it sits attached to the verb, but it can hop onto the question word (Co by pan chciał?). The full formation, including where -by lands, is on the conditional with -by.
Duration: na + accusative — na trzy noce
When the receptionist asks Na ile nocy? and the guest answers Na trzy noce, the structure is na + accusative to express intended duration — booking for a stretch of time. This is the planned-future "for how long", distinct from saying how long something actually lasted.
Rezerwuję pokój na dwie noce.
I'm booking a room for two nights.
Przyjechałem do Polski na tydzień.
I came to Poland for a week.
Wynajmujemy mieszkanie na miesiąc.
We're renting a flat for a month.
The key contrast: na tydzień (with na + accusative) means "for a week ahead", the duration you're planning for; without na, a bare accusative like cały tydzień means "all week long", the time actually filled. For checking in, you always want na + accusative. More on this split at the accusative of time and duration.
The numeral split — trzy noce vs pięć nocy
Here is the trap that makes Na ile nocy? worth a whole section. The noun noc ("night", feminine) changes its form depending on the number in front of it:
| Number | Form of "night(s)" | Why |
|---|---|---|
| 1 | jedna noc | singular nominative |
| 2, 3, 4 | dwie / trzy / cztery noce | plural nominative |
| 5, 6, 7 … 21, 22… | pięć / sześć / dwadzieścia nocy | genitive plural |
So you book na trzy noce but na pięć nocy. The rule: numbers 2, 3, 4 (and compounds ending in them, like 22, 23, 24 — but not 12, 13, 14) take the plural; 5 and up (plus 11–14) take the genitive plural.
Zostaję na cztery noce.
I'm staying for four nights.
Rezerwacja jest na pięć nocy.
The reservation is for five nights.
Byliśmy tam dwadzieścia jeden nocy.
We were there twenty-one nights.
That last one shows the compound rule: dwadzieścia jeden ends in jeden ("one"), so it behaves like 1 — but in this oblique time phrase you'll most often just hear the genitive nocy anyway. This 2-3-4 versus 5+ split governs every counted noun in Polish; master it on numeral–verb agreement. The question word ile ("how many") itself always takes the genitive plural, which is why it's ile nocy, never ile noce.
The reflexive zameldować się — "to check in"
"Check in" and "check out" are both reflexive in Polish: zameldować się (check in) and wymeldować się (check out). The się here isn't truly reflexive in meaning — you're not registering yourself literally — it's a fixed grammatical marker that simply belongs to these verbs, the same way nazywać się ("to be called") or spieszyć się ("to hurry") carry an obligatory się.
Muszę się zameldować przed osiemnastą.
I have to check in before six p.m.
Wymeldowaliśmy się rano.
We checked out in the morning.
The verbs share a root with meldunek ("registration of residence") — a reminder that in Poland zameldować się also means the official act of registering your address with the local authority. In a hotel, though, it's just "check in". The się can sit before the verb (muszę *się zameldować) or after it (chciałbym zameldować *się); both are fine. The behaviour of this little word is covered on the się overview.
Common Mistakes
❌ Chcę się zameldować na trzy nocy.
Incorrect — after 3, the noun is plural 'noce', not genitive 'nocy'.
✅ Chciałbym się zameldować na trzy noce.
I'd like to check in for three nights.
After 2, 3, 4 the noun is plain plural: trzy noce. And prefer the conditional chciałbym over chcę for politeness.
❌ Mam rezerwacja na nazwisko Nowak.
Incorrect — 'mam' (I have) takes the accusative object.
✅ Mam rezerwację na nazwisko Nowak.
I have a reservation under the name Nowak.
Mieć ("to have") governs the accusative, so rezerwacja → rezerwację.
❌ Zostaję dla trzech nocy.
Incorrect — duration is 'na + accusative', not 'dla' ('for the benefit of').
✅ Zostaję na trzy noce.
I'm staying for three nights.
Dla means "for the sake of someone". Time-duration "for" is na + accusative.
❌ Chcę zameldować w hotelu.
Incorrect — the verb requires 'się'; without it the sentence is broken.
✅ Chcę się zameldować w hotelu.
I want to check in at the hotel.
Zameldować się needs its się. Dropping it makes the verb transitive ("to register someone"), which isn't what you mean.
❌ Na ile noce pan rezerwował?
Incorrect — 'ile' always takes the genitive plural.
✅ Na ile nocy pan rezerwował?
For how many nights did you book?
Ile ("how many") behaves like "5+" and takes the genitive plural: ile nocy.
Key Takeaways
- Default to the conditional for politeness: Chciałbym…, Czy mógłby/mogłaby pan/pani…? — and remember it's gendered.
- Express booked duration with na + accusative: na trzy noce, na tydzień.
- The counted noun shifts: 2/3/4 → plural (noce), 5+ and ile → genitive plural (nocy).
- Zameldować się / wymeldować się ("check in / out") are fixed reflexive verbs — the się is obligatory.
