We loved staying at Esti’s flat. She was a very accommodating and responsive host even meeting us at the bus station upon our arrival from Bilbao. The apartment was new and as clean as advertised. The location was central (5 minutes from the beach 10-15 from old town). The only downside of the location was the construction in the surrounding area; however, this only affected the nearby aesthetics as we were not subjected to any loud noises while in the flat. All in all, I would certainly return to Esti’s flat on my next trip to San Sebastián.
