I've stayed in a good few apartments in Malta and this one rates highly. In terms of location it really couldn't be bettered: so close to the Sliema ferries and Tower Road, but far enough up the local street to make it acceptably quiet. The few metres walk to arguably the best coffee in Sliema (at cafe Berry) is the cherry on the cake.
We stayed in an unseasonable heatwave, made bearable by very efficient aircon. Also the wifi speed is great, so if you need to work online, then that's also made easy. The apartment has all the necessary modcons to make any stay - even an extended one - an attractive proposition.
And communication with James was excellent throughout: both pre-trip and while we were in situ.
I wouldn't hesitate to return or to recommend.
