Great studio, approx. 5 min walk away from the entrance of La Valletta and the main bus terminal (with buses going everywhere on the island). Located in Floriana, in a quiet (typical maltese) street with several mini-markets, it feels really good to live at the city's inhabitants' pace of life, far away from the tourist crowd. We stayed 5 nights and had everything we needed to cook when eating at home. Floriana is very nice to stay in.
We could not meet Ian, but he had everything prepared for our arrival and would always respond to emails during our stay.
I definitely recommend to stay in Floriana, in Ian's place (we had studio Apt #3).
