Absolutely brilliant location - I echo other comments about it being very central but also very quiet (it felt like it was a maximum 10 minutes walk to everything in Valletta).
We loved the views from the roof terrace, and the separate balcony for dining was lovely and very spacious.
I didn't find anywhere else with that much outdoor space so centrally located.
The open plan living was lovely - the kitchen was gorgeous and very well equipped.
We found the upstairs bed quite uncomfortable but just put the spare duvet under the bottom sheet and it was absolutely fine (nice size too).
Communication and check-in was extremely efficient from the outset. John who checked us in was lovely and very helpful.
Even the building we were in was absolutely gorgeous and had two entrances (one with a lift).
5 star stay and really brilliant. Would definitely recommend and stay again.
