The apartment building was fairly close by the Hotel reception and easily found. Unfortunately, the lock of the building front door was damaged and couldn't close, so anyone could enter the building at anytime. I've reported this at the reception, so hopefully this will be repaired soon.
The 5 person apartment itself was fairly spacious and well cleaned. The living room had a large table with 5 wooden chairs and a 2 person couch. Each room offered plenty of power sockets. The kitchen appliances worked well, but utensils and cutlery were lacking. To our pleasant surprise, there were two separate bathrooms. The showers were very comfortable, with clean towels, soap / shampoo and toiletpaper. The television was unplugged, because its Schuko plug doesn't fit into Maltese sockets. The WiFi coverage was decent, although internet speeds were just enough for basic web and messaging. The beds were clean and comfortable, but could use some extra blankets. There was plenty of closet storage space, with a small desk and mirror. Outside the bedrooms was a long and quite narrow balcony, behind double-glassed sliding doors. These doors sufficiently isolated outside temperatures and street noise, to enjoy a quiet night rest. During our stay, there was a one-time power failure which was resolved within the hour. Cleaning and towels were available daily, with friendly staff.
In general, we were quite happy with all facilities and amenities offered and would gladly return for another stay.
