The noise didnt bother me so much and the apartment was clean and well located. The shower turned cold after a few minutes of use, but it wasnt too bothersome in the summer days I visited.
The hosts are quick to respond and eager to help so I'm sure it can be managed during the colder months.
The studio is fully equipped and ideal for short term stays and people who like to enjoy long nights in Berlin. Overall a good deal for the price.
