We stayed at Abi's place for almost three months (Jan-March) and had a wonderful time! The apartment is beautiful, just like the pictures (if not nicer) and we felt at home from the moment we walked inside. There's everything you need, plenty of space, a great rooftop terrace with a view all the way to Valletta, and an adorable furry housemate downstairs. The area is quiet and not too touristy and gives you a good idea of real Malta life (unlike Sliema/St. Julians). It's not the most happening area, but there are plenty of nice restaurants within walking distance, just as supermarkets and smaller stores for every day need. Thanks to the ferry and tons of busses (both very cheap) it's super easy (and quick!) to get to Valletta and other areas (including a fast ferry to Gozo). The internet is a bit spotty sometimes, but worked well enough most of the time. Abi is the perfect host, super nice and responsive, and just a very pleasant person over all. If you're a cat person, I also highly recommend to stop by the shelter she volunteers at. :)
We loved our stay so much and were sad to leave. I highly recommend this apartment and would say it's very suitable for longer stays as well.
