Wonderful House, more than comfortable for 6 people, with lovely huge rooms and even a terrace. Also TV, bathtub, two king size beds.
The host was very welcoming and made us feel at home. Perhaps too much at home actually as we made excessive noise one night and it really wasn't appropriate, as there were complaints. I believe this was due to the way Maltese buildings are built - noise leaks everywhere even when in a house and with the windows closed, and also the neighbourhood really is very quiet. However in the end everything was resolved well and hopefully we didn't cause the host too much trouble.
Parking in the neighbourhood was very difficult, but we managed. We recommend driving around Malta, but only if you're a confident driver.
Sliema is a good place to stay as it's close to the capital, the airport, the party neighbourhood, although it isn't very special itself.
Overall, we had a great stay in Malta :)
