We had a very nice stay at Pedros apartment. The apartment is in the center of life at the beach in San Sebastian. The only thing you have to be aware of is if it is really hot, as it was during our stay, it is quite noise. The windows and the blinds are perfect but if closed it is rather warm. But I think this is the prize you have to pay if you want to see the beach and the sun set from your room. Take ear plugs and blind folds and the apartment is perfect.
Besides that, Pedros is a very helpful host. You have everything you need in the apartment. I only can recommend Pedro.
