Luis's place was perfect and just as described. Our check-in was very easy - we loved all the recommendations for coffee, restaurants, etc! Beds were very comfortable, and the views from the balcony were great.
One thing to note: we stayed in early October 2021, and there is construction happening in the next building over that starts at 8am each day. So it can be a bit noisy throughout the day (if you were needing quiet for children to nap or to sleep in).
Our stay is very enjoyable and we would choose to stay here again if ever back in San Sebastian.
