Everything was great since the first time that I wrote to her, she answered right away. The room and the bathroom were extremely clean and spacious. The location was great as it was close to the subway station (just 2 blocks), so you can easily get to the famous attractions. You also have a coffee shop right in the corner and many markets.
The area seems not to be that safe, but we did not have any issue at all and the subway runs 24 hrs so you wont have issues to get back to the airbnb.
It was a pleasant stay and Carethia was a great host!
