I would absolutely recommend Kevin's place! The apartment is in a wonderful location, in the middle of Valletta just a few minutes walk from Republic Street and St. John's Cathedral. It's a great spot for anyone who wants to see Valletta easily on foot. Everything is close by!
The space itself was perfect for me and my friend. The apartment was clean, well kept and had everything we needed. It even has a classic Maltese balcony that overlooks one of the pedestrian only streets outside.
Kevin was very helpful and quick to respond to any questions. He provides clear instructions on how to get to the apartment from the airport (multiple options!) so we didn't have any trouble finding the place.
If you're looking for a good spot in Valletta, definitely consider this one!
