Tres Piedras really is a stones throw from the beach. Walk across the park, over the road and then down the stone steps to the fabulous beach of Conil. Miles of sand, a wide beach and a very safe swimming environment for children and toddlers. Warm, clean water too!
The apartment itself is very well kitted out. It has things from rain umbrellas, to beach umbrellas, to ironing board, to wheeley trolley for supermarket shopping. Comfortable beds (a memory foam double mattress in one of the rooms, another double and a 2 singles in another room). A pleasant balcony with 4 chairs and a table and another balcony where you can hang washing.
The flat is 'friendly' for 6, but it's a town flat, so you'd expect not to be able to swing too many cats! We went with 2 kids and grandparents for most of the week, (grandparents left 1/2 way through).
On the 'full disclosure' front, the 2 negatives about the flat are; that there is no air conditioning, and the parking in the vicinity is pretty difficult in the height of summer months of July / August. In the summer, the temperatures are around 30-40 degrees, and air conditioning would have made a huge difference to comfort. Regarding the parking, general rule of thumb is to bring all you need (water, beer, heavy goods) at the beginning of your stay, park the car, wherever you can find a space, and just leave the car there for the week! You can then walk up to the supermarket (there's one around 500m up the road) with the wheeley trolley from the apartment on a daily basis to get groceries. Or walk into town (about 500m) for all the restaurants etc.
All in all, it is a fab little flat, for which you'd struggle to find something so close to the beach that is paralleled on comfort and convenience.
