After a long drive to Portland I arrived an hour after check in, only to be told the space would not be ready for another hour. Dave graciously apologized and offered to buy me dinner and a bottle of wine. The hosts want you to be happy, so you have to let them know what you want, asap.
The space is very nice - clean, simply furnished, modern and comfortable with excellent appliances, fixtures and linens.
Noise can be a concern. I think the hosts are figuring it out, but this is a basement in a lived-in-dwelling, so footfalls from above are unavoidable. The ventilation system can also be a bit noisy in the bedroom at morning startup, so let them know when you like to rise. Finally, there is a full-size refrigerator/freezer, so when it cycles you're going to hear it in the bedroom unless the door to the main room is closed.
Overall a very attractive private suite with very responsive hosts.
