My friends and I spent a week here and our stay was great. Self check in was really easy. The pool is bigger than what some of the previous comments say (definitely big enough for five adults to hang out - but you won't be swimming any laps!) and the shallow part is great if you've got little ones. The roof terrace is bigger than on the photos and provided amazing sunset views (but don't forget to bring some insect repellent with you). There's aircon in every room.
It's a great base for exploring Menorca - there are a few beaches nearby and Ciutadella is a 15-min drive away.
