Our stay was very pleasant. The aparment owners provided us the basic food products for "the start", and didn't count few extra euros for electricity (we exceeded a little bit apartment limit). The apartament was clean and spacious, kitchen fully equipped. Neighborhood was calm, and there was no problem to find a parking spot near our building.
I noticed only one cons – there was some kind of ventilator in room with two single beds, and because of that we heard noises from outside (TV sound from a neighbor, loud conversations etc.). Double bed room was quiet.
If you're looking for accomodation away from city noise and huge traffic – it's great place for you. Perfect with rented car, but there is also bus stop with direct connection to capital of Malta – Valleta.
