We are a US family of three (occasionally 4) that stayed in Toni Space for four months in the Fall of 2017 during the unrest. It exceeded our expectations and the other great reviews.
First, the location is excellent. It allows you to access the entire city becuase of the proximity to transportation. If picking again, I would live in this area.
Second, the apartment was clean and the neighbors were not very noisy (which can be common in city living, especially in Barca). If you have guests, you can probably fit five or six for a few nights with the layout (which is built for a couple and two kids).
Fnally, the host is ULTRA responsive. Any advice I needed was answered on WhatsApp immediately.
Overall a five star experience.
