I did not meet Maria personally, but our traveling companions did when they checked in before us. They said she was extremely nice and informative. The apartment was as described and very lovely. It was an easy walk to Charles Bridge and other major sites. We did not use any public transportation and were able to walk to several nice restaurants and all the sites we wanted to see. We were a group of 5 (2 couples and a single), so we each had our own unit. It was very comfortable as we knew each other well. The units also function as independent rooms, so you may be sharing the entry and laundry with others if you just stay in one. I would definitely recommend Maria's place and would stay there again.
