I will start by saying overal I would recommend this place. As an Airbnb superhost myself, I have high standards, so I'll leave a perfectly honest review, without being overly harsh, and hope it helps both the host and future guests alike.
The good: 1 minute walk to grocery store, less than 5 to main street/beach/dock etc. Quirky cottage feel that you expect in Avalon, with an amazing photo of a lady in the living room... don't know the history behind her but she is COOL. Nice side area of the house where we washed and dried our scuba diving gear. Brand spanking new carpet. comfortable enough beds.
The bad: zero communication from the host... like none. I asked a question when we arrived about the key, never got an answer, never heard anything out of them - classic airbnb managed by a property management group feel. no body wash or soap in either bathroom, just random shampoos. various condiments and beers (could be seen as a plus?) from previous guests. super cheap feeling pillows and linens. tired furniture in the living room. very small super old TV, no apps or chromecast or anything, only option is am hdmi cable that you can plug into your laptop if you have that capability.
General comments: bathrooms are super small but not misrepresented by the host. location was close to everything (as all of avalon is) but there were some noisy/late neighbors who live next door. not bad enough to complain, and we are the guests staying in their neighborhood so I get it, and I wasn't going to be a Karen. Checkout instructions say to take the trash out but the gate to the alley is locked, so you can't. kitchen seemed well stocked if you were going to cook there.
