I can't recommend Jan's spot enough. I gained more than just some time away from work and life here in the states while at his home in Mexico City, I truly came away with a lifelong friend. Jan's spot is perfectly situated within the city in what I would recommend and state as a more vibrant and fun general neighborhood than Roma Norte/Sur and even Condessa which are just a hop away. His place is airy, clean, spacious, and incredibly comfortable to stay and work from. Each week we had a house cleaner come and she would do everything from changing my sheets to cleaning my room, bathroom, and the entire house. The upper terrace is great for breakfast or lunch under the sun and the fact his place has a washing machine is a real bonus. Line drying is what is available here, not a dyer, just to mention, which doesn't matter much with the sunny days. The office to work from which is located directly across from your room is great as well with a chalkboard Jan has curated and posted up his favorite locations in the city to eat, drink, cafes, and more.
I spent nearly two months working and exploring this incredible city and loved every minute of it. I plan on returning again to hang with him and his awesome pup, Ñueca in the near future. Stay here, you won't regret it.
