I stayed at The Cala Del Sol Hotel, Las Playitas from the 16th to the 17th of May 2009.
The title says it all, but that would make this a short review :o)
We arrived 4 hours early, and Heidi the receptionist told us our room wasn't ready, fair enough, but she said it was well worth the wait, and she was right. Room 7401, looking out over the whole resort, absolutely fantastic. The room has it's own balcony, great for drying clothes over the railing, and the full length windows also have safety rails. Nice Sony LCD TV, and fridge in a built in unit, twin beds pushed together. Bathroom had a separate shower cubicle and a bath.
Reaching our room involved taking a couple of lifts, and a cable car, which was great, made the trip down to breakfast or the bar a little different. You can also walk down the access road, and steps to reach the main resort... but the cable car was more fun.
Sports facilities at this resort are excellent, the gym very well equipped, and you can also hire MTBs or proper road bikes. There's a full 50m pool, and 9 hole golf course, with a large pro shop. There's also a very nice infinity pool and sun terrace too.
On the opposite side of the resort there's the aparthotel, which also has another couple of pools and the resort shop. The shop is stocked with everything you need, more expensive than the Spar we had in Jandia, but still not bad, 50p+ for 1.5 litres of water.
The entire resort is spotless, the staff are always cleaning, and all of them are friendly and spoke damn good English. The resort, like many in southern Fuerteventura caters mainly for German visitors, and they too are friendly, and spoke much better English than I speak German.
Breakfast was buffet style and had a good selection of food, hot and cold. We went to the bar in the evenings, £6 for a Baileys and a Corona, served by Ester who was excellent, she kept the place spotless.
The beach is black sand, which gets hot, but is still soft, and due to the surrounding hills you didn't get the fierce winds that characterise Fuerteventure.
The Cala del Sol, and indeed Las Playitas as a whole was just excellent. I just can't fault it, the room, the view, the location... It's everything my girlfriend and I wanted.
