Being the first person to stay here I was a little bit cautious, but it turned out to be a fantastic decision - I ended up staying over double the original amount of time I planned.
Apartment: Hairys has a beautiful apartment. Everything is super modern, clean and has everything you need for a short or month long stay. Kitchen and bathroom were perfect, plus having laundry in the apartment was a bonus. Wifi was generally strong enough for Zoom calls in the living room (bedroom was a little less reliable). I loved the balcony and plants for fresh air and greenery.
Location: It's off Obrero Mundial which is a main road with everything you need (Oxxo, restaurants, farmacias). Parque Delta which has a supermarket is less than 10 minutes walk away. It's definitely not Roma Norte or Condesa, so don't expect a touristy area.
Host: Hairys is easily the best host I have had on AirBnb. Incredibly responsive and helpful with everything.
Zero complaints - overall A+++
