I can't say much except to agree with what many others have already said. It's an absolutely beautiful room in a great location. Super clean and organized. Run like professionals but with a personal touch (i.e, they have a great neighborhood map in the kitchen adorned with notes like 'best coffee' 'great Italian' 'best authentic German).

Note, the room is still in a shared flat (2 additional rooms), so your experience may vary depending on who you get and when they choose to come/go and use the bathroom. That's true for any shared flat, though, and given the price+quality+location, it's absolutely recommended!
