I always base my feedback on 3 things: host hospitality, the space (safety, decoration, cleanliness, etc), and my sleep.
In terms of host, previous reviews have spoken very positively about Nicole's personality. I've personally never met her (my fault; my flight was delayed and I got there late).
In terms of outside space, I was a little hesitant at first because parking is on the street and the neighborhood was kinda sketchy. Inside, very interesting! Nicole definitely has a great sense of art in both decoration and interior design. I can't speak much to this though, since my profession isn't art-related.
In terms of sleep, this is the key to my 5-star! I don't know what was (the candles, the long flight, the comfortable bed), but I had the best sleep at Nicole's place out of all Airbnb places.
