Joseph is a really nice guy, but he is not fond of cleaning. I am not picky, I have been backpacking Asia and Africa, but for European standards and the price take into consideration the rooms/bathroom were just plain dirty. This goes for linen as well. The apartment is situated in a quiet area just 15 minutes walk south of Valletta centre. It is basically a "nothing to do" area, but nice, safe and quiet at night.
We experienced a misunderstand at arrival as the host was not present at the apartment, but he later showed up apologizing, therefore not a big issue.
If you seek a fairly cheep place to stay in Malta this could be it, but if you are more than two persons a cheep hotel room would cost the same (and I bet it would be cleaner). No offense against the host, he was great.
