Alberto's place is in a fantastic location. It's right on the waterfront, where enjoyed sitting out in evenings with a glass of wine, watching the beautiful boats in the harbour. There are plenty of bars/restaurants along that stretch. You can walk 8 minutes down the road and catch the ferry over to Valletta for just €2.80 (return).
The apartment had everything we needed. There is a fridge with a small freezer section, a hob, microwave, toaster, etc. Also the air-conditioning was a life saver. Moreover, the building itself was amazing!
The only letdown for us was the mosquitos. The apartments was full of them, despite the fact the windows are all netted. Unfortunately we got eaten alive during the entire stay. I would recommend you bring lots of good quality mosquito killer, repellent and antihistamines.
Overall the place was good! Alberto was an excellent host, who was extremely friendly and helpful. He let us drop off our baggage before check-in so that we could go and explore the area. He also left us some chocolate croissants which was a nice touch. I would highly recommend him as a host!
