As far as airbnbs go, it doesn't get much better than this. A modern finished basement apartment less than a half hour drive from Palma. An exceptional value, I recommend staying as long as possible.
A few notes on transportation. There are no ride share apps in Mallorca, only expensive taxis and Bunyola only has 3 taxis. I managed to get by using public transportation. The busses are nice and fairly punctual, but time consuming. The frequency between busses can be up to 1. 5 hours. All trips (except Sóller and Port de Sóller) require taking the bus into Palma first, then additional busses from the main station.
Bunyola is a small town but it has a lot to offer. There's a small grocery store 10 minutes by foot that has everything you need. Alternatively, there are few nice restaurants around the main square. It's an excellent base for cycling. If you want to rent a bike I highly recommend Kilometro Cero in Sóller. There are two spectacular loops in the area and there's a boat from Port de Sóller that goes to Sa Calobra. Bikes can easily be put on the local busses. There is nice hiking in the area; Penyal d'Honor was amazing. Also, the historic train stops in Bunyola; perfect for a little trip into Sóller or continue on the tram to Port de Sóller.
It was a great experience, I hope to return in the future.
