If you're traveling with a large group, this is a wonderful property. Mallorca is a heavily visited island, and we were especially grateful to find that Colonia de San Pere is near the end of the road, so to speak. That means far less traffic and crowds, and a more serene environment. There are plenty of restaurants (though I suspect during the high season you'd still need to make reservations well in advance), a couple of small markets with all the necessities, and, well... not much else -- which suited us fine.
The house has 5 bedrooms (not the 4 listed in the advert) and two baths (three if you count the basement that serves for the pool). There's a nice living room and dining area, but we never used them, preferring to sit at the large table on the rear deck that overlooks the sea (though the house is not directly on the water). The view is fabulous. Two additional balconies give expanded views of not only the sea but the extraordinary mountains.
The whole house was immaculately clean, as was the pool. The bathrooms are modern and appear to have been recently remodeled. In general, the house in person is better than it looks in the photos.
The refrigerator and dishwasher and new washing machine are high end appliances. The kitchen is a little short on counter space, and I'm not a fan of electric cook tops, but everything is adequate and we prepared breakfasts and dinners for our group of 5 without problems. To cook anything really elaborate, you might need to visit the markets in Arta or Can Picafort.
There's the unexpected bonus of a work out room, complete with a pretty fancy resistance machine. The 19 year old in our group made good use of that.
