We had a great stay at Joaquín and Natalia's! It's in a really good location, very central with lots of restaurants and cafés nearby. They very kindly made recommendations about what to see and offered to book tickets for us (we had already booked everything so we didn't take them up on this but it was a very kind offer). The apartment itself was very clean and looked exactly like the photos, the only thing we noticed was that it could get quite loud first thing in the morning on the street outside, but this wasn't really an issue for us. They also let us drop out luggage at their reception nearby on our last day after we checked out so we didn't have to carry it around all day. We would definitely stay here again!
