Christine's place is beautiful! A very spacious apartment which is in walking distance of the airport. We had a flight at 6:40, so that was perfect. Valetta is easy to reach by bus. In our case we shared the bathroom and living room / kitchen with other guests, which was nice and interesting. It is very clean and there are a lot of tools / supplies for cooking available.
If you are looking for a nice place near the airport this is where you need to be!
