The apartement has very good location if you're interested in visiting different places in Malta then Msida is in the middle of everything - busride to Valletta, Sliema about 15 min, walk to Valletta takes ca 40 min. Taxi (Bolt) to/from aiport ca 20 min/13-14 euros, depending on traffic. Bus connection is very good and Msida bus stop is basically 10 m from the front door. Lots of eateries nearby, some small shops as well.
The apartment has all the basic stuff you need; we missed an adapter, french press and some teaspoons though. Everything was tidy.
It can be noisy from time to time when the neighbors decide to have party. We chose not to join the late night parties (probably it would have been the best way to get over it :))
Paola was very quick to answer the phone-call and messages. All in all we think its a good place to stay if you are curious to discover Malta.
