The BnB rooms with a/c are on the 3rd floor (46 steps, no elevator!).
The bedroom with en suite is spacious, has very good beds and is very quiet at night.
Regarding the cleanliness of the room, we can say that it was neat.
The WIFI is fast.
As an elderly couple (57/62), and for privacy reasons, we missed an extra table + chairs + a coffee making machine (or water boiler) in the bedroom.
Price/quality (20€ for 2p/day) = OK
Mosta is very well located to explore the whole island by bus. The buses are good, fast, cheap and reliable.
