Carlos's AirBnB is a true Roma Sur gem! Stay here, and you'll be in a fantastically convenient location - a lovely neighborhood and a safe building with a 24/7 front desk attendant. You'll also be close to a Starbucks and diagonally across the street from Los Parados (great al pastor tacos!). From the sidewalk outside the unit, we were always able to catch an Uber within minutes and explored all over the city comfortably and affordably.
The unit itself is full of perks. The hotel-grade bed sheets are very comfortable. The washer and dryer are a huge plus for extended-stay travelers like us. We also appreciated Carlos meeting us upon arrival and explaining how the keyless entry door works, as well as the windows. We were grateful for the extra towels and toiletries (shampoo, conditioner, bar soap, hand soap), as well as a hair dryer. The unit is decorated attractively (floating shelves, art, houseplants) in such a way that feels tasteful - not too crowded. If you are traveling as a couple and/or working remotely, you'll benefit from the ample space and the privacy/separation of the office (with a door), separate from the bedroom and the living room/kitchen.
We just returned to the U.S. today, and we're already ready to go back!
