The house is spacious and clean (good beds, clean bathroom towels - no kitchen towels though). As some other reviewers already wrote: the smell of the fire place is quite noticeable (it is best comparable to the smell of a bonfire, but then indoors). After a few days we got more used to it.
The house is located on a busy road, we liked it during the day as then we could see people passing by. At night it was sometimes rather noisy, also as there is a parking lot next to the bedroom. So bring some earplugs if you are a light sleeper.
Having a parking space was great, as finding a parking place in Deià is not easy.
