The apartments greatest plus is its excellent location in Valletta. It is located just a few steps away from the main bus station, from where you can easily reach a lot of places on the island. Booking went well and Franco sent us a detailed information of the apartment and how to get there. We did not met him personally but his mother in law handed out the keys to us and answered all our questions. All in all the apartment is a good choice to explore Valletta or the whole island. It looks like on the pictures, perhaps not that light. It was very clean and you find everything you need for your stay (hairdryer, iron, ...).
But I have to say that I would not stay again there in winter (15-17 degrees). The rooms are very high, due to the stone rather cold and there is no heating except the air-condition in the sleeping room. So if you want to spent more time in the apartment than just sleeping it is in this part of the year a bit uncomfortable. I guess that it is the opposite in summer :-)
