The apartment is in a very busy part of Sliema and the noise pollution is a problem if you stay there for a long period of time.
The flat is tastefully decorated but there is a fair amount of building works in the apartment block and adjacent to it. We were often woken up from 5.30 - 6.00 in the morning from drilling and banging somewhere in the building.
On the plus side, the check in process was very good, and if you encounter problems, they are quick to send around a handy man (we had quite a few which the agent put down to teething problems for a new apartment).
In the description we told there would be a weekly cleaning service. After we had moved in we were told this was a mistake! Not an issue for a short stay but we were there for nearly three months.
Parking is a problem in the area and we had to pay to park in the building (which is expensive) covered in chalk dust and only really suitable for very small cars.
We ended up checking out a few weeks earlier as after a huge amount of rainfall the building became very damp (which we were told by the agent is a fairly common issue in Malta due to porous chalk buildings).
