I first arrived around check-in time and getting keys into the apartment was easy - she left them in the front lobby. The lobby is staffed 24hrs with security and they are there to answer any questions you have. Getting into the apartment was easy because Alejandra left me some very detailed instructions on how to get inside. Once inside, the house is very spectacular. You can tell that Alejandra is an architect since the house has an awesome aesthetic and the details of the home stand out. There was 8 people in our party and we felt there was enough privacy for all of us. There are 3 beds and 3 bathrooms, 1 room has a private bathroom and the other two beds have separate bathrooms. There is everything inside of the house: wifi, towels, an Apple TV, first aid kit, etc. You won't have to worry about much. The top floor has a hang-out area for large groups and the view is just fantastic, and it's open to 11pm. You can also bring your own alcohol. If you want a great view of the city, stay here. Check-out was as easy as leaving the keys on the table.
Two things I wished I had known was that leaving the balcony doors open can allow mosquitoes to get in. Also, the pool was under maintenance so check with Alejandra before your trip. We wished we could've taken a swim since it looked beautiful.
Overall, I would recommend this place 100% and we would come back in a heartbeat. Mexico City is amazing and this place just made it alot better.
