We had a very good stay in this house in July 2017. The house is spacious and comfortable with a nice terrace area. It's in a very quiet residential area, and you will definitely need a car to get about easily. There is a shop within walking distance although this is quite pricey, it's good for essentials. There are a number of larger supermarkets a 15 minute drive away for bigger purchases.
The lounge is comfortable (although we spent most time sat outside on the terrace) and the large dining table would be good for families on holiday together.
Worth exploring downstairs to the garage - the best shower in the accommodation is hidden away down there!
Easily walkable from the house are a couple of restaurants/bars, and the sea is a short 5 minute walk down the road. The main beach is further away (20 minutes) with a few more restaurants/bars.
We found the house to be a good location to explore the local area. It's quite some distance from Palma (about an hour's drive, though mostly on good quiet roads), but a good spot to get to Arta, Alcudia and Pollenca. Nearby Colonia de Sant Pere is about 10-15 mins drive away and has much nicer restaurants and bars, and is a bit better kept than Son Serra de Marina.
Although we didn't meet Pepe in person, his communication with us was excellent with prompt replies to our messages both before and during our stay. Check-in was easy (even though we arrived at around midnight).
We would definitely recommend this house for a comfortable and quieter stay out of the busy resorts of Mallorca.
