Positives: Excellent communication, Romana met up with us as scheduled and worked with us on an earlier check-in, adequate number of keys for the apartments (note: these are two separate apartments on the same floor across from each other), and accurate number of beds and amenities.
Negatives: Entrance to the apartments feel very shady as entry requires a key into an alley-like dark hallway, some may feel the elevator is not as safe (max 3 persons), cleanliness is an issue as the building itself is obviously very old with cracked paint and a number of silverfish and cockroaches, we were not sure the bed linen and pillow covers were cleaned but this may have been due to their low quality. Another issue was one of the showers in the larger apartment leaked into the adjacent room and we had to either towel dry the floor or turn on the fan to dry the area.
I don't want to sound all too negative as I acknowledge I may have unfair high expectations but to me the value of the apartments was questionable as hotels in Prague are also relatively cheap. Unfortunately I wouldn't recommend this location.
