I had a great stay at Guillermina’s place! The location is totally walkable to all the best parts of Roma and Condesa, all while being located in a quiet and lovely part of Roma Sur, close to lots of cute cafes and supermarket. The apartment is very spacious and clean. Guillermina was always responsive and helpful. The washing machine wasn’t working during my stay and she was extremely proactive at getting it fixed asap. She was also very flexible with my last minute change in checkin and checkout times. I worked remotely from the apartment a few days and WiFi was excellent.
Only drawback is there is no direct, natural sunlight in the apartment, and the windows somewhat face other apartments, so you often have to keep the shades down for privacy. I think this would have been zero issue for me had I not been working from home for multiple days and just on vacation (I.e. out during the day.) I always appreciated the friendly doormen too. Totally recommended.
