We had a great stay at Rudy's apartment.
It is very close to trams and subway - in 20min you are in the city center - and there are supermarkets, convenience stores and a shopping mall close by.
The kitchen is small but you can cook meals in it - we did, everyday.
Rudy is extremely helpful and kind. Even with the fact that he was out of the country, he was very accessible and replied quickly.
We definitely recommend his apartment if you are going to Prague.
Thank you, Rudy!
