What a great place. My wife and I stayed with our three year old and had a great time. The pool is warm and clean and a few seconds from the front door. The apartment itself was really clean when we checked in and has enough to self-cater (pots, pans, stovetop coffee thing, hob, microwave plus a fridge). The bed is comfortable and we had a cot for our little one.
Nearby there's a small shop (two minutes' walk) and a parade of restaurants – our host told us which ones were good and was spot on. There's a beach about 10 minutes' walk away although to be honest we didn't really feel motivated to leave the apartment. The pool was empty or nearly empty most of the time (in June) so we spend most of our time there.
Up the road is Ciutadella, which has a bigger supermarket (10 mins' drive) and is easy to get to. If you have a car, parking is right next to the apartment in an allocated space which is easy to get in and out of.
Our host was really, really fast on communication – we've stayed in a few AirBnB apartments and never had a bad experience, but she is by far the best for getting back to us fast.
