This is a great central place. had a few nice bonus touches when we arrived, sparkling wine and chocolates free of charge waiting for us in our room.
We arrived after reception was closed but the key with instructions was left in a lock box on the front gate with code text to us prior to our arrival.
The room/apartment was plenty big enough for our stay (2 people for 2 nights). I loved the bed but that's a personal preference.
Loved Prague, if we return we would definitely stay at Diana's again and have no hesitation recommending to others
