The apartment is located relatively close to the promenade (about 15' walking) and about the same from bus stations, depending on where you want to go.
The neighborhood is relatively quiet, but it also helps that the apartment does not have windows facing outside. The windows face somewhere in between blocks and other apartments. This is also a minus, because the apartment is a bit dusty/unaired and the neighbors can be loud early in the morning. However, this wasn't really a problem for us, because we didn't spend a lot of time inside and had earplugs :D
The apartment is spacious, one bedroom can easily accommodate 2 people and the other one- which we did not use, has one smaller bed, perfect for kids or teens.
Kitchen and living room are spacious and have everything you need for a perfect stay- kitchen is amazingly well furbished and even has a washing machine.
Bathroom was very nice for us, as it has a LOT of towels available. This is good, since the apartment can get a bit humid and stuff might not dry properly.
However, guests can dry their stuff on the small terrace the apartment has in the back.
The apartment is a real bargain and it's well worth going there, the hosts are nice and helpful and all in all, I would rate this experience as a 9/10. Definitely book it if you consider spending some time in Malta/Bugibba!
