Where is the word for 'is' in this sentence?

Turkish doesn't have a separate word for 'is'. For 'he', 'she', or 'it' subjects, you simply put the noun and the adjective next to each other. Ev küçük literally means 'House small', but naturally translates to 'The house is small'.

How do we know Ev means 'the house' and not 'a house'?

Turkish does not have a separate word for 'the'. A noun standing alone as the subject of a sentence is generally understood as specific, so Ev means 'The house'. If you wanted to say 'a house', you would add the word bir (one) before it: Bir ev.

Is güzel only used for things that are physically 'beautiful'?

While it translates to 'beautiful', Turkish speakers use güzel much more broadly. It is a common everyday word for 'nice', 'good', 'fine', or 'lovely'. Calling a house güzel often just means it is a really nice place.
