As a first time user of Airbnb, I / we can really recommend it, as it has been a really positive experience.
In the beautiful sourrindings of Marina di Valetta, Haywarf, Pieta, we had deceided to book our stay on a lovely yacht, on which we had our own cabin with access to all common areas of the yacht (the galley, the salon, top deck)
Our host Matt, was extremely helpful and hospitable, and really made us feel at home during our entire stay.
On top of that Matt had arranged for a harbour cruise, onboard his boat which was a great way to see the sourrindings on our first night.
Overall it was just super experience, trying to stay overnight on a boat and almost getting rocked to sleep by the gentle waves.
On Malta you can almost find free WI-FI everywhere you go. On the yacht itself we werent able to catch the connection, however by going onshore and walking 50 meters, you can connect to Marina di Valetta's WI-FI.
The service and security personel who are hired by Marina di Valetta, are on duty 24/7 and everybody is extremely kind and helpful.
To sum it all up, we can defiantly recommend staying on "Forever" during your stay in Malta.
