The apartment was clean and comfortable and the street the apartment is on is safe. Having a security guard at the entrance to the building also added to this safety.
Make sure to take note of the address and check in instructions that are sent in the initial message (or confirm in advance) as they are different to those listed in the app. We followed the address and check-in instructions provided in the Airbnb app but the building is actually on the other side of the road. This wasn't a great start to our trip when we were jet lagged and it was dark and raining!
