The apartment is centrally located to many things, which is amazing. Great for seeing the sites. It was well lit and had a good communal area outside of the bedrooms, with a couch and table, for hanging out together.
Unfortunately, it's located directly over the Standard Cafe, which doesn't close until the early morning, making, especially two of the three rooms with beds directly under the windows, nearly impossible to sleep in since you can hear people yelling, throwing up, and singing all night long.
The apartment is on the second floor, but for luggage hauling purposes it's three flights up. Checking in was easy, but unfortunately we were only provided with one set of keys for four people, which was inconvenient.
The apartment seemed clean enough, but wasn't well stocked with additional towels, laundry detergent, or a working iron. The WiFi was slow, which seems to be a running issue in the places we've stayed in Europe so far.
Parking is difficult, but that was disclosed before renting.
This next bit is no poor reflection on the host, but our rental car was broken into the day of our departure (parked between a BMW and an Aston Martin just across the bridge), so if you're bringing a rental car know that it's always a possibility. However, to the host's credit, they offered us another flat to stay at after 18:00, after we checked out at 11:00, while we dealt with the rental company, police, and insurance. We wound up getting out of town before then, but it was kind of them to offer.
