Spent a very pleasant week at Club Vista Serena in mid December 2012. The site seems to be well established and seems to be getting to the stage where, despite being very well-maintained, it could probably do with a little tlc. It was spotlessly clean and the staff were exceedingly helpful and pleasant. The apartment was roomy with a lovely balcony for breakfast and lunch. Pool was excellen,t if a little "refreshing". Poolside snacks were limited menu but the tiny restaurant next door was wonderful value for money. On-site and nearby supermarkets were sufficient for most needs.
The site was quite a distance from the centre of Maspalomas ( about 40 minutes flat walk) in a quiet residential area which suited us. Taxis were readily available and quite cheap. Easy access to the more lively resort of Playa del Ingles.
Very restful week, would definitely go back again. I would certainly recommend as good value for money.
