There are a number of sites in the Madrid area but this is the nearest to the city, which can be reached by bus from the site.
Reception staff spoke English and were helpful. As you enter the site there are a lot of permanent caravans, which have rather a 'shanty town' appearance, but the touring pitches are in a separate area at the far end of the site.
Pitches are level, on sandy/gravelly ground, and of reasonable size. Some are completely sheltered by sunshades, the rest have a small sunshade per pitch to put your table and chairs under. This would be very useful in summer as Madrid gets extremely hot, but in January it was very, very cold!
Only one shower block was open low season but it was fully enclosed and heated, which was a boon. It was the smartest and most modern I have ever seen! Only one drawback - too hi-tec. The taps and showers all work by motion sensors, this means if you move in the shower the water stops! I found this so irritating I ended up using the disabled facilities (we were the only touring unit on site so I knew it would cause no inconvenience. ) These were the best I have ever seen, a whole separate bathroom with toilet, 2 washbasins at different heights and a shower with regular taps.
The washing-up sinks were also in a fully-enclose room but also had motion-sensitive taps, which meant you had to keep your hand under the tap the whole time you were filling the bowl!
There is also a swimming pool, restaurant and laundry room, though we didn't use them. We were only staying a couple of nights while visiting the art galleries in Madrid.
They've obviously spent a lot of money on refurbishing the shower blocks, but I think normal taps would be more user-friendly!
