This is a nice place and in a great location, close to the busy part of Sliema with bars, shops, cafes and restaurants all close by. However the flat itself is quiet inside - apart from the occasional loud bongs from the nearby church bell.
The flat is very clean and comfortable and I'd recommend a stay here. However, there isn't a washing machine (although there's a launderette nearby) and there's only one air conditioner.
Also, the living room is dark in the daytime, but if you're out and about in the day then it wouldn't matter. The bed is comfortable and the whole place was very clean, so it's a decent spot to stay in.
