This is the kind of space that I love to find on AirBnb: unique, homey, and a good deal.
I wouldn't recommend the space for: 1) folks with mobility issues 2) the particularly tall and/or wide (I banged my head on low beams, and I'm 5' 7") or 3) people traveling with small children. As many have mentioned, don't underestimate the stairs! That said, the space was charming, well-located, and suited our needs just fine.
The neighborhood in Rabat is quiet and peaceful. It's a quick walk to the charming town square and restaurants, and it's quite close to Mdina as well. Its central location made a great basecamp for exploring the island.
We rented a car, but there's a bus stop 3 minutes away and the busses are clean and reliable.
Paul was helpful and attentive to our needs.
For other winter travelers, I recommend being mindful of the lack of central heating! I wish I'd had some slippers or fluffy pjs for lounging in the space, as it did get quite chilly during our stay. But regardless of the more "rustic" touches, we'd certainly come back for another stay.
