I had a lovely stay at Rosa's AirB&B.
Communication has been very detailed.
Rosa and George have been great and lovely hosts, very welcoming and experts in giving suggestions on what to do on the island every day.
The location is more than great, if would give it more than 5 stars if I could. Two minutes walking from the busier city center of La Valletta, in a quiet street, very close to one of the ferry ports.
If I will ever come back to Valletta, I will definitely come back here!
