Absolutely recommend this spot! As a solo female traveler I can tell you I felt SO safe both in my stay as well as the neighbourhood. You will be close to cafes , restaurants, and practically everything. The aerobús stops so close to Sonder which is absolutely convenient. I can’t recommend this place enough- check in and check out was super smooth and the room is exactly what you need for your stay. Once again, everything is so close whether you want to take a bus or (I would recommend walking and soaking in the culture) walk, it’s a perfect place to stay!
P.S- Yes, there is noise outside (music, laughter, people in the street out till 3am) but I mean, it makes the city feel alive… plus you’ll probably want to be out and about too!
