Apartment is in a perfect location. Close to centrum, on the side of amazing park and walking distance to the beach (~20 min). Reachable directly by metro from airport. In a great neighborhood with various restaurants and bars.
Iñanki was kind enough to wait 1h to check me in (due to flight delay). He gave me many tips on what to see and where to go.
House is exactly as on pictures. Has many amenities and I didn't miss a thing during my stay. I'd definitely recommend it!
