The apartment is small but cosy, with amazingly comfortable bed and really nice shower :) a bunch of awesome breakfast food (such as toast bread, cereal, milk, etc) was left for us to enjoy.
The flat is perfectly located near tram/bus station, so you can get to the city center within 15-20 minutes. There is also a shopping mall located right next to the bus station with 24/7 Tesco.
Helena is a nice host who is always eager to help. Highly recommended for an eventful stay in Prague :)
