We had an amazing stay at Julio and Lucia's place. There were plenty of basic tools to cook with (although we did not use anything besides the coffee maker for hot water) and we had good water pressure and plenty of hot water for showers. We were out sightseeing most of the day but the wifi worked great when we needed it.
It is located close to Parque Mexico, is a short walk to restaurants and stores.
Lastly, the apartment itself is beautifully decorated and we felt at home instantly. We appreciated not having a TV and there were plenty of spaces to read and enjoy a coffee and pastry. Mexico City felt fairly safe when we were there but the apartment is situated in a gated community for those who appreciate the extra precaution.
We would absolutely stay here again the next time we are back!
