We had a fantastic stay at Guillermina’s apartment.
Communication with her was easy via phone calls and WhatsApp throughout our trip.
The apartment was a little hard to find but our host was on hand to help with directions.
The space itself is well equipped, nice decoration throughout and very clean.
The apartment is in the centre of town so can be very noisy in the evening but the windows are good at blocking out most of the noise.
Would recommend for a lovely stay in San Sebastián.
