This was a great place to stay and Sidsel was a great host - quick to reply to all our questions.
Be aware that this is a top floor apartment and those six flights of stairs can be really intimidating at the end of a long day of sightseeing - or when you realize that 50 lb suitcase isn't going to walk up on its own.
The apartment is not air conditioned but there are so many windows to open that temperatures in low 20s C weren't a problem except in the loft area.
We ended up using bus transportation to most of our sightseeing but more fit travelers could easily walk to the major tourist areas. The neighborhood felt lively but safe and there are restaurants, cafes and grocery stores very nearby.
