First of all this apartment is great for group of friends or family of 4 people. We were there 10 days.
We arrived on apartment by taxi (25€ from the airport). Alberto showed and explained us all. Than we went to the beach (around 15 min walking) and at first glance it was difficult, but later ran quickly up and down:)
This apartment is very clean and comfortable. Cooking zone have enough dishes to make anything.
Also you can rest on a backyard in the evening, its very comfortable and quiet place.
In conclusion, if you want to spend time in a cute place surrounded by small number of tourists in a real Spain outskirts, you definitely should choose Alberto's apartment!
