We really enjoyed our stay in Bellavista! The location is beautiful and perfect if you want to go to the quieter parts of Mallorca. Maria's house was enough for us, the outdoors was beautiful and there was a lovely pool! The inside just needed a little bit of general maintenance.
I would suggest that a car would be a good idea as the nearest food shop is a little far to walk and there isn't many restaurants nearby other than one which is 100 meters down the road.
However, once we figured out the bus service times and stops we managed to use this without a problem to go to many places.
We had a few issues with some of the appliances in the house not working, but Maria did reply quickly and came and helped us out the best she could.
