M&M house is really nice. It is close to a lovely beach and has a nice swimming pool. There are some things that we didn’t like as much: it is quite remote, so there are no nice restaurants nearby, the next bigger supermarkets are in Porto Cristo. The kitchen utensils are quite dated and the cabinets don‘t smell particularly nice. The view from the balcony is lovely, but it would be nice to have some extra shade, so you can sit there more hours of the day.
There is a bar at the bottom of the hill with pretty loud music and talking in the evenings, so that is also something to keep in mind.
All in all, if you have a car and are willing to drive in order to go shopping and find good restaurants, M&M house is a good place to stay.
