The flat is located in a supremely tactical position for visiting Donostia, on a walking distance to pretty much everything. Everything inside looks new and polished, beds are comfy and nothing leaves to be desired. I never got to meet the host in person, but they were always very communicative and provided lightning-fast responses to any question or matter. Check-in procedures were a bit weird, but they worked out flawlessly. In my experience, the other guests preferred to stay shut in their rooms all the time, so I had all the common area to myself and it never felt crowded, but that depends on luck I guess, like in any shared apartment. In general, I believe this flat is a very good option for its price.
