We (family of three) stayed at Nai's place in Condesa for over a week. This has been the best AirBnb experience we've had. Nai's penthouse is bright, large, centrally located, and has great views. There is one bedroom and Nai had also added some privacy screens for our son so he could have his own alcove and bed off the living area.
Nai is a fantastic host. She welcomed us at the flat, gave us a lot of tips on what to see / do, helped organized our trip to xochimilco. Nai is extremely responsive over texts/whatsapp.
Condesa is a great neighborhood, and I would recommend Nai's place to anyone who travels there.
