Clau and her co-hosts are incredibly responsive and were able to accommodate us with a very last-minute booking and early check-in. Everything was clean and had good water pressure.
The location is perfect - right next to the parque and easy access to Roma and Condesa.
The apartment itself is definitely a little aged but otherwise has most of what you would need. Unfortunately, given the layout, the sunlight doesn't really reach the living room and one of the bedrooms. This wasn't a big deal as we were only staying one night.
I'd definitely recommend Clau's place for a shorter visit.
