Staying at Anna's place was perfect. I'll try to put into details, because her place deserves your stay :)
Location : some reviews said it's somewhat far from city centre, we consider it's perfect.
Right in front of apartment, there is tram no.18 which will take you to almost all of thinkable destinations in Prague.
Downstairs there is small shop (which also sells day-pass ticket!) adding the convenience.
Room : Just perfect. Hot water is running well for a refreshing shower after roaming around the city.
Host : Anna's hospitality and responsiveness towards her guests are five star. She assisted us during our stay with all the best she could.
Don't miss this place :)
