This apartment is gorgeous, with reclaimed wood touches and other thoughtful and beautiful decorations. (The chandelier in the main bathroom was my favorite!) The hosts have stocked items like toiletries, coffee, hair drier, laundry detergent, extra blankets, etc. We felt safe while we were there - just need to be vigilant at night when coming and going from the apartment. We were approached on the street by men several timea as we were coming and going - just people asking for money and cigarettes. We (two women) felt safe walking around the neighborhood during the day, but would not recommend doing this at night.
You don't hear any noise from the tattoo shop underneath. You do get a little street noise and can hear every word that people say in the parking lot (we were in 2C, which faces the parking lot) and there were bands playing in the parking lot during our stay for the one year anniversary of the tattoo ahop which was LOUD. But overnight was fine. There are white noise machines in the bedrooms. Its a jack and jill bathroom set up, which isn't totally clear in the photos. Second bathroom is in the back with the laundry. We were extremely pleased with our stay and would definitely stay at this location again. Hosts were very responsive and friendly!
