This is by far the cleanest airbnb we have ever stayed in (which is about 20 so far)! It was so clean. Martin and Joanne were fabulous hosts and thought of everything. They met us at the apartment with a key when we arrived around midnight and even had milk, bread and eggs to get us started, which was great because we have three small kids and they were starving.
The location is very close to St. Paul's bay and a lot of restaurants and markets. One thing to note is that it is hard to find parking at night on the streets, although it's free! Just something to be aware of.
We came in December and although the weather is nice outside, we were not ready for the cold indoors (it's a limestone building meant to trap cool air in--obviously--it's Malta and has more hot days than cool), but Martin & Joanne came and changed all the sheets to flannel ones for us and left a heater which made all the difference in the world. They really were super hosts and the place was great. Highly recommend.
