Dave and Clara had great communication with my husband and I leading up to our arrival from Montreal. We stayed for two nights as part of our honeymoon. Dave met us at the AirBnB and showed us the studio, and he even talked us through a map of places to see during our short visit.
The first night was a bit miserable though, since the AC is controlled by the adjoined neighbor studio and there was an issue causing our room to be 80 degrees through the night. We communicated the issue with Dave & Clara, and Dave immediately responded and came over, but found the AC fine in the adjoining room. There wasn't much to be done but add another fan to circulate the warm air or open the door to the outdoor sitting area we shared with the neighbor apartment. (We didn't do this because the neighbor was another stranger staying via AirBnB and we weren't comfortable with that.) We strongly considered booking another place the next day, unwilling to sweat through another night.
Dave was so understanding and was willing to reimburse us for the second night if we chose to go elsewhere, but we couldn't afford to book a hotel room so we decided to stay again. And we're so glad we did! Dave had done some ductwork and when we returned from our sight-seeing the next evening, the room was cool! We slept great and were thankful for such a kind and accommodating host.
