We never met Nicol, but she was wonderful. Very communicative, proactive & helpful - careful to ensure that we got in (complete with photos of the building, entry, etc), that we had everything we needed (a note came in well after we'd arrived to make sure we were ok) & a list of restaurants, bars, etc.
We came from the airport, used public transport in the winter dark & we found it + got into the building & apartment with no issue.
For the price, Nicole's apartment was PERFECTLY located. Only a few minutes walk to the Metro, to the ferry to Museum Island (went to the Vasa & ABBA Museums) & to Old Town (Gamla Stan) (had a free walking tour there).
Strong wifi, great bathroom, hot shower, fridge. Very warm place too.
Note: there are rather a lot of stairs (3rd fl apartment) & the washing machine & dryers are for the whole building (so not in Nicol's apartment), but it's free & easy to use (we did 2 loads). Nicol's apartment was so warm that everything was dry the next day.
Excellent!
