We stayed 3 days at Ritas place and felt very comfortable. The room is as descriped, we very much liked the nice balcony and the room always had a good temperature although it was hot outside, so we didn't need the AC.
The apartment is in a very good area and in walking distance to sightseeing places like the catacombs and Mdina. Dingli Cliffs are also close and you can take a hike to get there.
