The Uliv Airbnb was great! It was in a wonderful location right in the middle of Roma Norte. Quite literally most of the top restaurants and bars are within a 5-10 min walk of the building. The building itself is entirely an Airbnb building. To get into the building you have to buzz and the security guard will let you in. You don't have any keys and your unit will have a keypad lock. The security guards are nice but do not speak any English.
The unit itself is nice. It has a very modern design and personally a bit too modern. The walls are still the original concrete and it looks more unfinished than modern. There is a small kitchen with a mini-fridge. The bed is comfortable and the shower is really nice with good heat/pressure. There is no closet and a few hangers near the bathroom. The lighting in the whole apartment is a bit minimal and it can be pretty dark. There is a good amount of noise that comes in from the street and your neighboring unit. But this is the price you pay for the ideal location. There is a rooftop but there are no lights up there so at night it's useless. It's unfortunate because they could have done a lot more with the rooftop space. There is also a laundry in the basement and bikes you can rent for free (although the bikes don't come with locks so it makes them difficult to take places).
Communication with Santiago is really easy and when one of my lights wasn't working he came over to fix them. Overall, it was a great Airbnb and ideal if you want to stay in Roma Norte. Slightly overpriced for Mexico City but that's just my opinion.
