Just back from 4 nights at Becky’s apartment and I can’t recommend it highly enough! The location is spot on, close to the Sliema ferry and Fort St Elmo (the best historical site and museum in Valletta, really well thought out), a stones throw from all the bars and restaurants but on a quiet residential street without lots of tourists - Valletta is so small you could stay in any part and be within 15 mins of anywhere you want to go!
Becky was incredibly helpful, always replying very quickly to any questions, suggesting boat tour operators (we’d recommend Hornblower cruises), booking our airport taxis and accommodating our request of extra towels for the boat trip.
The studio itself is lovely with everything you need for a very comfortable stay. Some may find the bed a bit soft but it was blissfully comfy to us and we were grateful for the addition of blackout curtains.
All in all, a great apartment which I’d definitely recommend if you’re going to Valletta!
