The location in my opinion is perfect. It's in the Gros area about 10-15 mins walk from the old town which is ideal. You can stroll in when you want but don't have to deal with loads of crowds and noise when you don't want to. The area itself is very safe, close to one of the beaches (not too far from the other) and has some great local bars and restaurants. In short, it feels more Spanish and less Touristy.
The apartment is great, plenty of space, well laid out, two good sized bedrooms a small balcony and great bathroom & shower. It's immaculately clean and served by a lift.
Then you come to Ainhoa, who is lovely, fantastic contact, really nice and super helpful. She has even helped find a jacket that I left on the bus to Biarritz. I would 100% stay again! Thanks Ainhoa.
