We had a great time at Claudio and Angela's place in Mexico City! The apartment is in a central location between Condesa, Roma, and Downtown. The space is big enough for approximately 6 people comfortably (more if you want to squeeze). It was also tastefully decorated! Claudio and Angela were able to provide great tips on where to visit, and also assisted with airport pickup.
The only downside was that there is currently (February 2018) heavy construction outside on the roads throughout the day and into the night, which makes it quite noisy. I'd suggest checking to see if this has been completed prior to booking your visit.
