We have been a whole week in Marks apartment in Valletta and had a great time there. The building itself is stunning but wait until you see the flat itself and its harbour view from the balcony.
The apartment is in very good shape, was absolutely clean and inviting. We fell in love from the minute we entered (and opened the blinds). The lofty style makes it light and clear, the floor is so enjoyable to walk on, the kitchen is perfect for preparing breakfast/ lunch/ dinner. The bathroom is really large - it was a real joy to take a shower after long days of sightseeing in Valletta and its surroundings.
There is only a 10 minute walk from Floriana to Valetta (upper Barrakka Gardens) and all the sights. And the walk is beautiful for itself.
The harbour view was the best view in an airbnb apartment so far for me - relaxing, beautiful and inspirational. And you do not only have the best view of the Grand Harbour but also the best view to the cruise ships (up to four a day). Me and my friend could have stayed here much longer than planned. If you book harbour loft 1 you will definitely have the best time in Valletta and Malta.
