The location of the apartment is perfect, it's just in the middle of old Valletta and there are plenty of good restaurants just around the corner. Ferry to Sliema is also easily reachable. If you need to use any taxi services, I can highly recommend downloading a Taxify app, as it is very convenient especially in the old town, where finding a specific address can be a bit difficult for the taxis due to confusing numbering of the buildings. We were a group of 5 adults and for us Maria's apartment worked very well. It was also very easy to communicate with Maria before our stay and she provided us good instructions for the arrival in advance. Thanks Maria for a great stay!
