Hela's place is great! Very accurate to the photos and description. It's actually bigger than the photos make it look. The location is fantastic and easily walkable to most places you'd want to visit. The kitchen is equipped with everything but a microwave, there's a dishwasher, a washer and dryer (separate), extra towels and bedding, a decent size elevator, and the building felt very safe.
My only complaints are that the internet is very slow and the welcome guide could benefit from having a few more instructions (like the stove and dishwasher, although we eventually figured them out).
There were also some small flies throughout the apartment that we couldn't get rid of (looked a bit like drain flies but we're not fly experts). They were present from the beginning of our stay. The apartment was very clean though so we're not sure where they were coming from.
Otherwise it was a very nice stay and I definitely recommend it!
