There are many old buildings, cathedrals, museums there. From Buda there are wonderful views of Pest and the river.

Three men came to... New York for... holiday. They came to... very large hotel and took... room there. Their room was on... forty-fifth floor. In... evening... friends went to... theatre and came back to... hotel very late.
«I am very sorry,» said... clerk of... hotel, «but... lifts do not work tonight. If you don't want to walk up to your room, we shall make... beds for you in... hall.» «No, no,» said one of... friends, «no, thank you. We don't want to sleep in... hall. We shall walk up to our room.»
Then he turned to his friends and said: «It is not easy to walk up to... forty-fifth floor, but we shall make it easier. On... way to... room I shall tell you some jokes; then you, Andy, will sing us some songs; then you, Peter, will tell us some interesting stories.» So they began walking up to their room. Tom told them many jokes; Andy sang some songs.
At last they came to... thirty sixth floor. They were tired and decided to have... rest. «Well,» said Tom, «now it is your turn, Peter. After all... jokes, I would like to hear... sad story.
