Good: A lot crammed into the room, air-con excellent, large comfortable bed, light and airy, fridge/cooking facilities. Nice quiet area and building.
Bad: Minor, but an unpleasant smell in bathroom if window shut, also a bit cramped in there.
Location: Nice area, but a bit far from centre - not far to metro (10 mins walk), but line 3 has limited connections.
Unique: We never saw anybody - check in/out is automatic, and there is no housekeeping - but loads of towels, loo roll etc provided, so all good.
