The room is pretty good value for its excellent location. The fact that it's on top of a bar that sometimes plays live music could be considered a positive or a negative i guess. I personally quite enjoyed drinking a beer there listening to a local band of bandoneons playing there :) BTW, the bar only accepts cash!
The access to the bathroom is not the most comfortable, since you need to carry a key to open a locked door and go through what seems like a private office to get to it.
