We have stayed at Maria's place between October 16th and October 23rd and have enjoyed it a lot. Maria was waiting for us at the house with some nice pastries and showed us around. Also the communication before our arrival was always fast and helpful.
The house was clean and fully equipped. As mentioned in other references, indeed the road to the supermarket is either via very long and steep stairs or via a road full of cars. There is no real footpath down the road. This is a bit dangerous, so don't let children go there by themselves.
From the house to Palma in a car is only 15 minutes. Also if you would like to go to a big supermarket, by car it's just 6 minutes away. We had a rental car, which we could park safely on our own property behind an automatic fence. We had some problems with the jacuzzi, which were solved a day later.
We have enjoyed our stay with 2 adults, 3 teenage children and 1 baby. For the baby we had a nice babybed and chair. We would recommend this place if you are going to visit Mallorca!
