Carsten is a great host! Right at our arrival he showed us the neighborhood: Some supermarkets, good restaurants and a beautiful park. Besides that, he also gave us precious information about the public transport in Prague and some good places for sightseeing.
Coming to the apartment, it was really nice and clean. Everything you need was there. Shops and bus station were in walking distance. It is also to mention that the apartment is located between two beautiful parks which you should definitely go to.
Overall we had a great stay in Prague in Carsten's apartment and are very keen to come back!
