We stayed here for 2 months so we really experienced it all! It was myself, my husband, and our 1 year old. First, Juan is a superb host. He is very communicative, easy to get along with, and if it is within his control he will fix/solve any issue. That is a huge perk of this location.
The views are incredible from almost every location in the condo. I went to rooftop bars that didn't have as good a view as this location. It never got old to look out into the city and watch the sunset. Truly breathtaking!
What we loved about the location is that it is between two wonderful parks, which was great for our baby. It is also less than 5 minute walk from the famous street, 'Avenida Amsterdam'. Restaurants, shopping, bars, anything you need is walking distance. If you want to leave Condesa, then Uber is the best bet from there because it is not conveniently located near a metro/subway stop. There is a bus stop nearby but it has limited routes.
It is located in the same building/corner as three bars and a concert venue. Across the street there is an Irish pub and a french restaurant that plays live music. This is the main street that people come to party in all of Condesa! So you can probably guess the noise level. Yes, it is loud. Even with the windows closed. The guest room is a lot quieter so that is where we put the baby to sleep. But we found ourselves also sleeping there more than 3 nights a week to get a break from the ear plugs and white noise app (which helped some). During our stay there was live music or DJ from Wednesday/Thursday night till Monday night. So a bit more than just the weekend.
The elevator can be finicky too. We had a few weeks that it worked perfect. The rest of the time we had to go to the 12th floor and go down a short flight of stairs. Not a big deal at all. For 3 days during our stay the elevator didn't work at all and of course it happened after we went grocery shopping. So we had to go up 11 flights of stairs with baby, stroller, and groceries. However, the front desk staff and the elevator technicians were super kind, apologetic, and tried to work as quickly as possibly. They were very open to telling us all the details and tried to help us as much as they could.
Lastly, note that there is no AC which is fine during the colder season. However, when it is hot outside it can get pretty warm since heat rises and you are on the 11th floor. Luckily, there is a fan there now since we told Juan it was too warm for the baby to sleep. He quickly got a fan to us. But you may need to take advantage of the beautiful neighborhood and take a walk while the condo cools down.
Overall, I think it is perfect for a regular vacation stay with adult friends/family where you can be in the middle of the action and have a really great time with the best views in the city!
