Filip's place is perfect for a long term stay for one person, it's close to the city centre yet far enough to be very quiet in the evening. I stayed at Filip's place for a month and explored the area around it quite a bit. It was really nice as Vyšehrad is only 10 mins away and there's some great bars by the river also only 10 mins away!
I have to say that the hot water run out quite quickly in the flat when showering or doing dishes. Other than that, the place was perfect for what I was looking for. I would recommend this place for 2 people for a short term stay or 1 person if you're planning to stay for longer.
