Nick is very much available through email, SMS or the phone. Indications received by email were complete and accurate.
His customers in the apartment below ours held a very noisy party on our first night: Nick contacted them twice to bring the noise level down: first time was for music level, second time for the running and the shouting. They left the next day, and the following customers were quiet. I was told that some people in Toronto rented AirBNB flats to throw parties, which is bad for both users and owners.
The bathroom's cleanliness was not up to our expectations. Nick made sure the cleaning crew came back on the next day to correct this. He even refunded the cleaning fees.
Location was perfect for us as we were visiting friends 10-minutes away.
