Great place in general. Nice view trough the window and all landmarks (in that area) are reachable by walking. There are great places to eat as well.
Moreover isolation is good too, I didn't hear neighbors at all, of course maybe they were quite too. Flat had all the utilities for cooking, coffee and nice balcony.
Won't be complaining on humidity because Malta in general is humid.
However the flat took some time to heat up, it would be great that in early spring/winter guests could arrive in warm place. The only thing what really disappointed me was dusty parts, moldy shower cover and dirty wardrobe. Also in the balcony sitting are was dirty as well. These are the things to work on. All in all - totally worth the price!
