This was a good home base for out family of 3 in San Sebastian. Apartment isn't big, but it feels big with 3 bedrooms and 2 bathrooms, a full kitchen and living room. Very comfortable. Beds were comfortable; showers and bathrooms were both great. Right upstairs from a few good grocery stores and the neighborhood has a wealth of food choices. It's a short walk to the middle of town, which is just across the bridge. Gros is its own neighborhood, with a different vibe (more residential, less commercial) than the other side of the river; but, you also feel separate if you want to spend a lotta time at La Concha Beach or in Old Town, for example. It's about a 15-minute walk to those areas.
Everything in the apartment worked well and the check-in process and communication with the host was top notch. He met us at the door and was easy to communicate with the entire stay.
