I stayed here with four friends for four nights. It's a huge, beautiful, well decorated apartment in a lovely, green, safe and pleasant neighborhood surrounded by excellent restaurants and cafes. The apartment was bigger than it looked in the photos and extremely comfortable, with great furniture and really nice art. There are multiple areas where people can spread out to get work done, nap, and/or relax, so it's great for a larger group. It was very clean and had everything we needed, including big fluffy towels and a well-stocked kitchen with all the basics. Erika and her team were super responsive, accommodating, and easy to work with. They made our trip very convenient.
The only two (very minor) issues with the apartment are that the wifi signal can be a little weak in certain locations or when lots of people are trying to use it, and although this particular street in Condesa is fairly quiet, there is some street noise, so it may not be best for extremely light sleepers. But we had a wonderful stay, my friends were all very impressed, and I would highly recommend this place. I'm already trying to figure out when I can go back.
