Loved our stay at Elena's lovely villa flat. The apartment itself was well equipped, tastefully decorated, and VERY clean!
The location is a pleasant 10-15 minute walk from the beach, and maybe another 10 minutes further to the old town where all the great bars, shops and restaurants are located. That said, if you are not a walker, then the bus stop is less than a block away and will get you into old town in less than 10 minutes.
Our communication and interaction with Elena was a joy. Such a nice woman, and totally on top of making sure her guests feel at home while staying in her lovely villa. If I ever have the opportunity to come back to San Sebastián, I hope to find this very desirable Airbnb option available!
