Villa Mercedes is an extremely spacious, beautifully fitted and very well-equipped house. It's rare to find a villa with a pool of this size too (although the depth is not sufficient for diving). Given that we were there at Easter, it was worth paying a supplement to have the pool heated, as the wind had quite a cooling effect. (Note that a childproof barrier is provided if required to prevent access to the steps and pool.)
Dave and Julie were very welcoming and helpful during our stay, and very discreet on the odd occasion they came to clean the pool. As others have said, the welcome pack was like nothing we'd ever experienced before - and we've stayed in a LOT of villas over the years! Fabulous - loads of fresh fruit, cheese, ham, three types of wine, bread, biscuits, crisps, milk, eggs, water, etc. - all you need to start you off! It was a real bonus to find supplies of tea, ground coffee, sugar, olive oil, herbs and spices, foil, film, and even dishwasher tablets - none of which Julie would allow us to replace. All we bought for the house was laundry detergent and softener, and a top up of kitchen and toilet rolls.
Note that, unsurprisingly, care must be taken to prevent crumbs, etc, attracting ants.
The bedrooms and bathrooms have plenty of storage cupboards and drawers, as does the kitchen - which is equipped with every possible gadget and accessory. The floors are fully tiled throughout, so good for those with allergies - and easy cleaning. High quality bath, hand and beach towels are provided, along with numerous chair and lounger cushions and throws for the outside area.
Our (adult!) children had much fun with the Wii, and it was great to follow the Commonwealth Games on the large screen TV. Wifi was good where it worked, but didn't extend to two of the bedrooms, or onto the veranda.
We were delighted with the peacefulness of the area, well away from the tourist hubs on the coast, and with the villa being just on the edge of Nazaret, the little supermarket (that sells just about everything) is a few minutes' walk away, as are two excellent restaurants. Teguise (the small, pleasant, welcoming former capital of Lanzarote,) can be reached in about 25 minutes on foot, mostly on dirt tracks, which makes for a nice walk in the evening. The track and path network also provides several routes for early morning/evening running.
Other than the minor limitations of the Wifi, the villa was perfect; we would recommend it very highly!
