I had a great experience in Clare and Alan's place! The studio apartment is super nice, with a traditional Maltese balcony in a very quiet street. The kitchen is fully equipped. The bed is confortable. The flat was very clean. There is only a small table in the balcony, which is not the best if you are two or if you have to work. The wifi worked well.
The position? Close to Valletta, around 10 minutes from the entrance of Valletta, and around 20 minutes from the Campus of Valletta. Moreover, close to the flat there are a lot of mini markets.
Definitely suggested, especially for a single traveler.
