First the positives - the location is fantastic. Walkable, close to all kinds of things to do, an easy trip to museums and historic sites. And the beds are AMAZING. Probably the most comfortable bed I've slept in that wasn't my own. It was also very clean and the hosts were nice.
The negatives - the place needs some maintenance. There is soggy drywall near the bathroom, the bathroom wall leaks when it rains, the doors are super flimsy, and the breaker trips when you run the heater and the microwave at the same time (we had to re-set it twice during a 2.5 day stay). The place could stand a real couch. The one provided is super uncomfortable. The dog upstairs is VERY loud at all hours and it sounds like he is in the apartment with you. If you are a light sleeper, this is NOT the place for you.
But for the price and the location, we were satisfied with our stay. A few upgrades and repairs and it could be first rate.
