Dani (co-host) was always quick to respond and was very accommodating! The space itself was really nice and clean. The location was great, close to the metro and walking distance (less than 30 min) from most tourist spots (Sol, plaza de mayor, art museums). It was also close to a few different grocery stores if you needed to pick up anything.
The apartment is one floor up so it was a bit noisy from the street, but I wouldn't really fault the Airbnb itself for that. Something to consider if you're a reaaaaally light sleeper but I stayed for 2 weeks and it wasn't too bad! Also the blinds in the living room are on the outside, so would recommend asking about how to let it down because there's no curtains on the inside (bedroom had curtains).
Overall it was a great stay, for a reasonable price!
