Great flat in a very central location in San Sebastian. Beach and old town are both 5min walk with a public parking just in front of the flat. The terrace is defintiely stunning and gets the sun most of the day/afternoon with an amazing view over the city's roofs. Rest of the flat was as described.
A few things could have been better: the place didn't feel clean to a professional level and some kitchenware sets should be replaced (eg. 3 wine glasses for a flat of 4). Just those little details that, for the price, would make the stay perfect.
