Excellent hosting, good location (also parking-wise; free parking within walking distance, and I definitely recommend a rental car), nice laid-back Mediterranean energy throughout the house. We were even offered a late check-out, how nice!
The only thing we found not so good is that the main street is quite noisy in terms of traffic between 7am and 11pm, and you'll want to keep the window a bit open for fresh air. But this is not a problem if you're not a light sleeper (and don't have earplugs).
A very nice place to stay in Palma.
