We have enjoyed our stay at this Airbnb a lot. It's very close to the center of Palma, you can basically walk everywhere from the apartment. We have only been in touch with Xavi; he was very kind and helpful and had some good tips for the area. The apartment itself is quite big and has a good bed and bathroom.
I would definitely recommend this apartment for a short stay in Palma. If you're a light sleeper it would be wise to bring some earplugs - it is a bit noisy.
