We enjoyed our stay at Guido's place. Communication was good, and the check-in process was smooth. While the building itself is located on a very busy street and might not appear the most inviting at first glance, the unit itself is actually relatively quiet (being at the rear of the building, facing a less busy street), comfortable, clean, and just as described, with most of the essentials for a short stay, if somewhat spartan. Perhaps the best aspect of this flat is its central location, with most of Roma and Condesa reachable within a 10-20 minute walk, not to mention public transit and an Ecobici bike share station just around the corner. Overall, it's a solid value for anyone who's happy with simple, clean, and convenient accommodations. I'd stay again.
