Daniel is a great host, carefully with your needs so don't hesitate to contact him in any case. His flatmates are cool too.
His flat is indeed in one of the quietest neighborhoods of Palma, very accesibile by walking and good connected with several Bus lines (8,7) to the city center, with various supermarkets in a walking distance and a nice little park nearby.
The room got a good lighting and a big cosy bed. The balcony is a great bonus. The kitchen is well equipped with everything you need to cook your meals. Therefore the walls seem pretty thin and the doors can make noise if you don't close them carefully.
I would recommend Daniel's place especially if you want a place to sleep and you're all day long outside discovering the city/island. My Tipp go in the north of the island - you will be impressed.
