Great location and very useful to have the secure parking too. Flat was clean and spacious but the bathroom really let it down for us - it was hard to get in and out of the bath and the tap wouldn't allow us to have a shower. Some of the fixtures and fittings are a little cheap, for example several electric sockets and light switches simply fell apart exposing live wires, not ideal for curious children! We found it hard to relax having to keep watch our toddler didn't go near them.
Apart from those important points we did like the apartment and would recommend it so long as they were sorted out.
We especially loved San Sebastian and the owners were very helpful and communicative in making sure we enjoyed our stay.
