first of all I slept on a very poor mattress. (more an old sofa...) second in the guestroom I stayed in there was a problem with draft. the payment was a bit of a hassle too due to the lessors cumbersome communicationstyle. plus the bathroom was incredibly low-ceilinged and thereby only convinient if you are shorter than 1.70m. even if the flat in total is an impressive location this was not my cup of tea.
