The place was clean, quiet and located in an area full of shops, restaurants and bus stops (which are very important if you want to get around Malta). It was well equipped (oven with cooker function, toaster, hair dryer, power socket adapters, electric kettle, tv) but lacked a wardrobe or a drawer to put our clothes in. The only drawer available was basically a small nightstand where we could put our glasses, wallets, books, chargers, but nothing more. There were two small racks, one for towels and one for clothes with few hangers, but that was it. We also had a problem with hot water, as there was none in the morning for two days and nobody told us, that the building has limited hot water (or if there was any other reason, we've never found out, but never have asked). The apartment was pretty chilly in the night, but it was mid february.
Frank and his wife are very nice, friendly and helpful. Any questions asked via app are answered right away. We could leave our luggage after checkout which was also great as we had a whole day of sightseeing before our flight back.
Apart from keeping our stuff pretty much everywhere as there was no place to keep it and taking two cold morning showers everything was really great.
