Vbl was very available and supportive. We forgot the key inside the room and they reacted super fast although it was fairly late. Location is as well amazing and typical to La Valette.
However we were a little disappointed by the service. Common parts were clearly not taken care of i.e. the kitchen was filthy and standards were not reached concerning the cleaningness of the room. Furthermore, construction work seem to take place specifically in the morning so between this and the bells + the fact there's a Lotto office right next door that makes it seem you've got people in your room (if you are on the street side), it is a quite special experience. I totally recommend if your main concern is being in Valletta and you do not care about the rest.
