Tôi đã để xe ở trước khách sạn.

Đã is a past/completed-action marker. In Tôi đã để xe ở trước khách sạn, it shows that the action happened before now.

A useful way to think about it:

• Tôi để xe ở trước khách sạn = I leave / I left / I park / I parked in front of the hotel, depending on context
• Tôi đã để xe ở trước khách sạn = I already left/parked the vehicle in front of the hotel

Vietnamese does not mark tense the same way English does, so words like đã help make the time clearer.

Literally, để means to leave or to put, and xe means vehicle. Together, để xe often means to leave one's vehicle somewhere, and in many situations it can be understood as to park.

So this sentence can mean something like:

• I left my vehicle in front of the hotel.
• I parked in front of the hotel.

Depending on context, it may sound slightly broader than English park, because để xe focuses on where the vehicle was left.

Not necessarily. Xe is a general word meaning vehicle. It could refer to:

• a motorbike
• a bicycle
• a car
• another vehicle

In Vietnam, if no other context is given, many people may first imagine a motorbike, because that is very common. If you want to be specific, you can say:

• xe máy = motorbike
• xe đạp = bicycle
• ô tô or xe hơi = car

Ở introduces a location, so here it means something like at / in / on, depending on context. In this sentence, ở trước khách sạn means at the front of the hotel or in front of the hotel.

You can think of it like this:

• trước khách sạn = in front of the hotel
• ở trước khách sạn = at/in front of the hotel

In many cases, ở can be omitted and the sentence still sounds natural:

• Tôi đã để xe trước khách sạn.

Adding ở makes the location phrase a little more explicit.

Here, trước khách sạn means in front of the hotel.

The word trước can mean:

• before in time
• in front of in space

In this sentence, because it follows a place noun (khách sạn = hotel), it is clearly about location:

• trước khách sạn = in front of the hotel

Vietnamese does not use articles like a, an, and the the way English does.

So khách sạn can mean:

• a hotel
• the hotel

The exact meaning depends on context. If the listener already knows which hotel is being talked about, English would normally translate it as the hotel.

This is very common in Vietnamese: nouns often appear without an article, and context does the job.

The basic structure here is:

• Tôi = subject
• đã = past/completed marker
• để xe = verb + object
• ở trước khách sạn = location

So the pattern is:

Subject + aspect marker + verb + object + location

That is a very common Vietnamese sentence pattern. English is similar in some ways, but Vietnamese often uses separate words like đã instead of changing the verb form.

Yes. Those are often more directly equivalent to park a vehicle.

Common options:

• đỗ xe = park a vehicle
• đậu xe = park a vehicle
• để xe = leave/park a vehicle somewhere

A few notes:

• đậu xe is very common in the south.
• đỗ xe is often preferred in the north or in more formal usage.
• để xe is also very common, especially when focusing on where the vehicle was left.

So all of these can work, but the nuance is slightly different.

Yes, very often.

Vietnamese frequently leaves out time markers when the time is already clear from context. So:

• Tôi để xe ở trước khách sạn.

could still mean I parked my vehicle in front of the hotel, if the conversation already makes the time obvious.

Using đã just makes the past meaning clearer.

Not always. If it is already obvious who is speaking, Vietnamese often drops the subject pronoun in conversation.

For example, in context, someone might simply say:

• Đã để xe ở trước khách sạn rồi.

However, tôi is perfectly correct and is useful when:

• you want to be clear
• the subject is not obvious
• the sentence is more formal or careful

Also, tôi is only one possible pronoun. In real life, Vietnamese speakers often choose pronouns based on age, relationship, and social context.

Yes, it is understandable and natural.

It suggests that the speaker left/parked the vehicle in front of the hotel. Depending on the exact situation, a native speaker might also say:

• Tôi đã để xe trước khách sạn.
• Tôi đã đỗ xe trước khách sạn.
• Tôi đã đậu xe trước khách sạn.

So your sentence is fine, and a learner should mainly notice:

• đã marks past/completion
• để xe means leave/park a vehicle
• ở trước khách sạn gives the location
