We stayed for 12 nights in an appartment which was more than big enough for the two of us.
I think this is more of a place for families with children....since we were pretty much the only couple without kids.
Overall, the residence holidays has everything you need. The apartments are equipped with a kitchen so you can cook your own meals, there is a large balcony to enjoy the summer evenings, and the wifi worked in our apartment (something you can't expect in every holiday establishment, we've experienced in the past).
The staff was very friendly and helpful. So all in all, we had a great time.
The only small 'negative' point is the location of the apartment.
There's not really anything to do around the apartments, and it's about a 20 minutes walk to the town centre and beach.... And it's not really a nice walk, because you have to walk past a few narrow roads without a proper sidewalk, so cars and motorbikes go past you pretty close and fast, felt a bit unsafe.
But i think they use a shuttle bus in the summer months (we were there just outside of the season so the bus wasn't in service yet)
