Umberto was an excellent and responsive host and the apartment was great - really superb location in the heart of Valletta, very well fitted out, modern and well kept, really cool balconies with great views, fresh towels and cleaned daily. My two tips to help future guests would be:
1. the listing says free parking on the premises but this isnt correct and the nearby streets are always full. However its fine because there is a huge modern convenient MCP public car park a 10 minute walk away, with lots of space and only a max daily charge of 10 euros. The only bit that needs a bit of planning for guests is getting your cases the 10 minute walk from the car park to the apartment when you arrive.
2. the bedroom is up a fairly steep metal spiral staircase. Again, absolutely fine (with a wonderful light panoramic view bedroom as your reward!) but you need to be OK with such stairs.
