This is a wonderful place to stay, right in the very heart of Deia, with a cafe literally on the doorstep for breakfast, lunch or dinner, and lots of restaurants and bars just a few steps away, without the house being too noisy. The rooftop terrace is also wonderfully private despite being in the centre of the village. There is also a small supermarket just 2 minutes walk away selling everything you'd need. Parking is pretty close to the house, and you can get a parking permit from the local town hall for €20 (though not sure how easy it would be to find a space in high season).
The house was well appointed, with washing machine, dryer and dishwasher, and two excellent showers.
The house is a little dark - presumably a big advantage in high summer, but not perfect later in the year. The terrace has an amazing view, but you don't get any from inside the house itself. When we went (in November) there was also some smell of dampness, which didn't matter much to us, but could be more important if you are sensitive to this.
Deia is a truly amazing place, and a great base for visiting the surrounding mountains - the walk down to the Cala is wonderful, and the Cala itself beautiful. Definitely also worth doing the Cami de s'escolta walk next to Can Costa - great walk with kids, with stunning views. The kids also loved the sandy beach at Port de Soller, and horse riding on the beach near Can Picafort (near Alcudia).
Double Take Burger ("El Bar") just across the street was also a great place - fantastic cocktails (try a passion fruit margherita or whisky sour), and very tasty burgers.
Bruno was also very approachable and helpful - an excellent host.
