A couple hundred meters from Yoan's apartment you'll find a Carrefour supermarket, Casco Viejo -- the old city -- and Atxuri station where a tram will take you across the river to the nearest Starbucks in 5 mins (it's 600 or 700m walking) and the Guggenheim Museum (2km walking) in 10 mins. The location is excellent. The apartment building itself is on a steep hill, but there's a public elevator that takes you right to the foot of the building from the main avenue along the river.
While the balcony is not private -- the apartment is after all shared with the hosts -- the views are panoramic and impressive.
The room you're renting is comfortable, neither small nor large, just enough for a big bed and side tables. The bathroom is private, but off from the shared hallway/entrance to the apartment.
Yoan is a great host, which explains the reviews he has for this room. For breakfast he prepared an assortment of fruit, a couple of pastries and some juice & coffee, which is a nice touch and gives you an idea of the kind of host you're dealing with.
Neither here nor there but the room, bathroom and apartment in general was very clean and the attention to detail -- usually rare in short term rentals -- was noticable & appreciated as a guest.
Overall great experience.
