The Waterton AirBnb is a large, attractive unit, with well-documented beautiful views, which is a key reason we chose this location. Bear in mind that if the weather is rainy and/or cold, you won't really be able to sit outside and enjoy the view; I think it would be fabulous during the summer.
The building was quiet and felt safe. The unit was clean, furnished in IKEA modern. What was lacking were the little touches that make it homey that we have had in other AirBnbs, such as snacks and drinks. I didn't think the kitchen was well equipped; we couldn't find a cookie sheet for the oven.
One thing to note if you have more than two people in the unit ... the bedroom wall does NOT extend all the way to the ceiling, so there is a lack of privacy if you have others sleeping on the pull-out sofa.
Our flight was delayed and there were guests checking in that day, so the host said we could not leave our bags there. If that happens to you, use BagBnb, for $6 apiece, and there are locations throughout the city to store your luggage.
