The location of this flat is amazing! It is in walking distance to almost everything and really close to public transport in case you want to see something further out. Also it is really really quite und cool (it was 33°C when we were in Prague but our flat was never hot!). So that's a BIG plus. We only used to flat to shower and sleep so everything was okay. But it is not very well equipped in case you want to cook or anything. It also could be a bit better taken care of.
Aleksandr is a good host. He sent us a lot of useful information for Prague and we had no problems with our communication.
