Our family stayed at Alegranza in March of 2012, and had such a great time that we returned in March of 2013. We booked directly with Alegranza, and reserved a 3 bed/3 bath condo for our group of five. Imagine our delight when we arrived and found that we had been upgraded to a 4 bed/4 bath penthouse!
The unit was extremely clean, and contained lots of basic items like dishwasher detergent and dish soap, beach and bath towels, and so on. The lower terrace had a couple of loungers and a dining table with chairs, while the upper penthouse terrace had a hot tub, several more loungers, another dining area, a couch, BBQ area, and so on. Views from both terraces were great; we were able to see whales while sitting out having our breakfast, and you can look in both directions down the coast. One of the bed/bath combinations was up on the top level, while the other 3 were on the main level of the penthouse.
The unit contained a washer/dryer, dishwasher, several TV's (some with SKY TV), and had a fairly well equipped kitchen. Our only suggestion would be to have more plastic tableware available, as we were concerned that a pottery dish or glass item might be broken during use. Each unit at Alegranza is individually owned, so the unit may not be decorated exactly as the photos show, but we were not disappointed.
Alegranza has three pools (the middle one is heated, while the other two are cool; great for a refreshing dip on those really hot days), two hot tubs, a small gym, two fire pits (great for family marshmallow roasts if you are travelling with kids), a small cafe type restaurant, a restaurant for fine dining, and more. Certainly all of the amenities you would need for a relaxing vacation, and although we saw lots of cars in the parking lot, the pools were never crowded, and you were never without a lounger.
If you want to swim at the beach, we would recommend travelling to a beach like Chileno, for which you would need to have a car, or take the bus or a taxi. I believe the beach down the hill in front of Alegranza is not safe for swimming.
The concierge service (Lucy and other staff) are absolutely amazing, and will print out directions for you, recommend restaurants, make reservations, book tours, and so on. They always greeted me with a smile and my name, making me feel welcome.
Javier and his staff are certainly running a quality establishment, and we hope to be able to return again in 2014!
