We had a fantastic stay at Umberto's place. The (3) terrace's are amazing, a fantastic hot tub, with views of the city and the sea. The location is right in the heart of Valletta.
The flat is fully equipped to make sure your stay is comfortable.
The service Umberto provides is great. Communication was excellent and he allowed us to keep are bags at the flat before and after check in/check out which was so helpful for us.
