Firstly, I echo everyone’s comment and appreciation of Loyola’s personal time and communication, both before (he very kindly measured his garage so we knew we could fit our car in) and during our stay.
The suite has all you need to enjoy a city break in lovely San Sebastián, such toiletries, and a mini fridge with milk, juice & beer.
Loyola’s home is situated in a very quiet, smart and safe residential area. The walk back from old town (which yes is up hill and has a number of steps) is only about 20 minutes but helped us work off all the pintxo & txakoli! But you could get a bus which would cut out the hill.
