The apartment is perfect! My boyfriend and I stayed in Marias apartment for just very little time, like 4 days but it was amazing. The flat is well equipped with everything you need. The communication was great, although we did not meet Maria but a friend of her. She helped us with all the question we had. We were super happy because our objective was to relax and see the island. So we rent a scooter and discovered the island.
One thing you need to know is that you will not have wifi or any phone connection. For us, it was fine, because we did not want to be connected. Anyway, it is a great choice and we will definitely come back. Loved it!
