My friends and I stayed here in August during high season. We had some issues with the tenant below us, David. However they were resolved by the owners, Claudia and Vanessa. I was also told that this flat would no longer be rented out on air bnb. Given the situation we had with David, this is probably a good choice for the owners because we felt a bit unsafe and almost left half way through our stay. So for that reason I wouldn't recommend this flat until the issues with David were resolved. Otherwise we loved the flat, it was big and spacious for 3 of us. Location was great during the day, but very quiet and dead at night. It was slightly scary walking home late at night because the streets were so quiet it was a creepy feeling. It's right in old town of Palma and is on a side street from where the shopping area is. But everything pretty much closes at 11 pm and the area turns into a ghost town. Still walking distance to other neighbourhoods which are more lively in the night.
Only downside to the flat was the lack of air conditioning during August. I wouldn't recommend this if the heat bothers you.
Otherwise the price we paid for the size and location was great.
