The apartment is beautiful and totally worth its price.
Hosts are great, communicative and very helpful.
Inside the flat offered by Elena and Kira, which is situated in clean and calm neighbourhood (near center of the city), you can find modern design, useful tools, comfortably beds and nice bathroom.
I sincerely recommend this place if You want to visit the Prague and stay there for a few days. You can get there by public transport like a tram or a subway, whose stations are very close to the apartment.
