Eugenia's and Diego's place is a perfect place for you to enjoy your stay in Mexico City.
There were 5 of us, and the place is actually big enough for at least 7-8. It is a beautiful place, with modern touches, and a great layout. Plenty of bathrooms, sitting areas, and nice views from several areas. The place is well constructed, so you do not hear noise from other bedrooms or other units. The elevators work great, and a doorman greets you any time, 24/7.
If you are up for cooking, it is fully stocked, but with all the restaurants within 5 minutes walking, there is no need to cook.
The beds felt new and comfortable, and the sheets and towels were very clean. We stayed for 8 days and had a complete house keeping clean-up in the middle of the stay, and it felt like we arrived at a new place.
When we had questions, Eugenia quickly answered and was available via text or phone.
I would not hesitate on recommending this place for your stay.
Cheers
