We spent a night at Lasse's. The flat is in a 5th floor (get prepared to train your muscles!) and it is an old Danish building, that's the reason why the shower is placed in the basement and the toilet has only WC (no sink, so you would have to use the kitchen sink to brush teeth and wash face).
It is a cosy place, all equipped. We used the TV to plug our laptop and watch a movie and also the stereo to listen to music while chilling. We had a nice time.
Besides, Lasse is very friendly and responsive. We could check-in before and he waited patiently for us since we were late.
The bed is comfortable and the flat is warm.
I could recommend it for short stays.
