I can highly recommend planning your stay at Sarka's apartment. It is very cosy, and comfortable. Equipped with everything you will need (coffee machines, fridge, TV, stuff for cooking, etc.), very comfortable matresses and super quiet at night. Included in the price you will find a beautiful view on the east part of the Prague from roof windows :).
The apartment is on the 6th floor in regular block of flats, 20 mins by a walk from Vysehrad, within 4 minutes to the tram stop by a walk. Lots of supermarkets, playgrounds, restaurants, bakeries/confectionaries. Totally worth it!
