We had a great stay at the flat, it was modern, clean and quiet and location was very good for short walk to the centre and also central bus station (for Bilbao airport bus and other bus services). There is also a lovely coffeeshop just outside the flat which was great for morning croissant and take-away coffees. Communication and check-in/check-out was very easy and efficient. Additional guests for part of our stay were easily accommodated which was greatly appreciated. Many thanks for a lovely stay in San Sebastian! :)
