Rick's flat is just amazing! It is huge and full of small details. It is nicely decorated. I specially loved the kitchen. The beds are comfortable and the huge library is just impressive!
The apartment is really close to the city centre. It is easy to get there in few minutes and it also has good connection with trams. Supermarkets are also in the nearby.
Regarding the hoster, Rick made things really easy for us. He gave us a lot of information about where to eat, contemplate art and he also suggested some places where to be far from tourists, mission almost impossible in Prague.
