This was a wonderful experience and we are very happy to have stayed in Marius' and Oana's place.
Zabbar is a very quiet (but not deserted) village with friendly population of local Maltese people. The apartment is 1 minute walk to a closest bus stop and a mini market and 20 minutes by foot to The Notre Dame Gate and the bazaar we found there.
The apartment is very clean and stylish and has all the amenities we needed. Bedroom and living room have independent air conditioning systems, and a terrace is as nice as it is shown in the pictures.
The hosts, Marius and Oana, are very responsive and caring. Although we've booked a couple of months in advance, they started talking to us immediately, sharing the information we might find interesting to help us plan the visit better. When we arrived they spent some time with us to share lots of useful information about the surroundings and Malta itself, as well as giving us some hints as to what we might want to visit nearby. Since we didn't manage to see everything we wanted during our stay and we do plan to come back, we hope we'll manage to book with Marius and Oana again. Honestly, they were the best Airbnb hosts we've met so far. 100% recommended.
