The villa was large large and easily suitable for 12 people. We where with 6 adults and 4 kids (1-3 year old) and it was perfect. We rented a car (which I would advise) that got us in 10 minutes to Pollenca and 15 minutes to Alcudia. Taxi was 23 euro's for 4 persons single trip to Alcudia if you want to dine out. The pool is pretty large, only thing we need to get used to was the taste of salt water in it but nothing else. Limited airco use costed us a little more than 100 euro's for 13 days.
For parents: The kitchen was our morning 'feed the kids' place that had a door to the living room so that the rest could keep on sleeping while the frenzy began. The swimming pool was visible from the patio so we could see if they got too close to the pool.
