This hotel (which is actually north of Candeleria proper) is a solid 3.5-star accommodation, with on-site spa, fitness, restaurant, bars, swimming pool, laundry service, in-room A/C, safe, terrace, and bidet. It is a bit on the older side, but definitely not run down. The clientele tends to be retirees from Spain, UK, or Germany. The entertainment is geared to this demographic, and is understandably campy. The food, for the most part, is very good! Try the tasting menu, too! It's a small upcharge, and worth it.
The grounds are very clean and the eco-garden and waterfall is actually quite impressive. Plenty of places to lounge around outside. Across the street is access to the sea. A short walk South takes you to the boardwalk and the sea and more black snd beaches.
If you want a drink or a meal offsite, there are lots of good options. There is an ATM right up the street, a 24-hour convenience store right next door, a supermarket a few blocks away (El Mercado) with everything you could need at very good prices. If you must, there is a McDonald's further up the street.
Bus stop is just north of the hotel. Plentiful rental car place.
I personally think this is a great base of operations for a Tenerife adventure. It's easy to get to by bus or taxi or rental car, and it's relaxing and full-featured.
