The apartment was really great - clean, cozy, comfortable. Mark was also very responsive, and helped us add another person after the booking. Unfortunately the walls weren't very soundproof, so we could hear people walking and talking upstairs. It has not interrupted us during our first night. However on our second night, our neighbors upstairs were hosting a party that involved continuous drumming, singing, jumping for about an hour around midnight. We contacted Mark via phone and message. About 30 minutes after we informed Mark, the noise started to cool down, and reached normal quietness around 1am. This was definitely not what we have expected from an apartment that required the guests to stay quiet after 10pm.
