This place had the biggest bathroom/shower space I'd seen in this price range, and working AC. The beds were comfortable enough. Great light blocking curtains. There's common indoor and "outdoor" areas. There's also a common kitchen, but didn't make use of it. You do occasionally hear the metro pass by, but as a light sleeper did not have any trouble sleeping here at all. Room 13.
The staff were all great, very friendly, alert, and helpful.
The main entrance is only accessible by having a staff member open it from inside. You need to knock on the door physically. There is a keycard reader, and a camera doorbell, neither of these seems to do anything. We arrived to find two other guest poking at these (I'd done the same before) when I asked if they had knocked, they said yes, so I took their word for granted. After waiting for a bit, I tried knocking on the door myself, and the staff opened the door almost immediately to the other guests astoniment.
The door closing was a bit confusing, you need to use your card on the door latch when leaving the room to be able to close it. This lead to new guests slamming doors until they figured out the process. At one point, I noticed that if I tried to open the door after closing it it would give after two attempts and reopen. Not sure why, but I had to keep checking the door after closing it to avoid potentially leaving it unlocked.
Perhaps explaining the room doors closing and main door knocking (don't use keycard or doorbell) to guests on arrival may be a time and confusion saver for tired guests.
The internet was down when we arrived, but it was fixed the next day by noon.
