The place is very clean. Despite being central, you can't hear noise from the street. It is close to everywhere (ie/ public transit, major attractions, and etc).
There are 3 rooms in the apartment: 2 rooms for Airbnb and 1 for the host. The host is really quiet in her room. However, depending on who is staying in the other Airbnb room, you may hear phone buzzing, door slamming, or their full conversation. The first guest that stayed next to me was pretty quiet except the occasional phone vibration, which usually ends before midnight. However, I had trouble sleeping when two people replaced the previous guest.
The host is an old lady who is very talkative. She can have a conversation with you for hours without trouble.
The mattress is an old spring mattress. I have some back problems previously because of an office job. The mattress increases back pain.
The place is a great value for what you pay for given the location and amenities.
