Me and two friends spent 5 nights in Prague at Pavel's flat. We were greeted by Jan who showed us around the flat and gave us keys and instructions for check out. The flat was fine and was suitable for our needs as we we're spending alot of time in the flat. It is very well located and there lots of good places to get breakfast, coffee, dinner and drinks within 5mins walk.
One thing which I would suggest needs improvement is a real black-out blind in the bedrooms...the bedrooms are in the loft space with the window in the ceiling. In the larger bedroom the bed is directly under the window. There is a blind but it only paritally covers the window, it means there is no escape from the early daylight which is a spotlight over half the bed. So bring an eyemask.
