I'm very glad that I rented this room. It was perfect for a solo traveller (like me) and would also be good for a couple or a pair of friends. Paul was a very friendly, helpful host, and his family were charming as well. The room was homely but comfortable and I had everything I needed from breakfast to bathroom. One thing that I must mention is the location - you're right in the middle of historic Valletta, in easy reach of everything.
The only slight negative that I would mention is that the room has no air-conditioning, and so I had to sleep with the windows open at night (obviously Malta gets hot in the summer). It can be noisy in the streets and there are mosquitoes about. Personally this was not a problem for me, but it might be something to consider. For the price that I paid though, it was excellent value overall.
