Check in instructions are misleading. Got the code for the front door, entered the code, intercom said "door opened", but in reality it was still locked (upper lock)! Turned out that lock required a flat key, but to get the flat key you also need to enter through the front door! Ridiculous.
Luckily another tenant (who already checked in and had a key) came after 10 minutes and opened the door for me, so I could enter and get my own flat key... What if I arrived very late at night - what would I do? Too risky to book such flats, beware. If you arrive late at night - better book a hotel.
As far as the flat is concerned, lets talk about positives:
1. Good location, quiet area, close to the underground.
2. Everything is new and clean.
3. Tea bags, cups, kettle, nesspresso machine, coffee pods - very nice touch, loved it.
Negatives:
1. Shambolic switches / electric wiring. You turn on bed lamps - ceiling fan turns on (why?). You turn on ceiling lights - bed lamps turn off. Very random stuff, purely guessing game. Ceiling fan kept turning on even after I turned it off couple of times. What a bizarre situation.
2. Narrow bed (140 cm wide). Not ideal if you are a couple (even if you are very slim / short people). Pillows are too thick, not really comfortable.
Overall, just OK for 1 night and very slim / short people (and as long as the landlord sorts out the entrance door).
