Katy's place is beautiful and the neighborhood is quiet, so on the whole we had a good stay. However, there were a few things that we think others should be aware of.
First, the smart lock feature may be more hassle than it is worth for short term guests. There is the time involved in downloading the app and getting it connected to your Airbnb acct. Then there is the possibility of a glitch that prevents this setup, as happened to us. When we let Katy know about this, she gave us a code to open the door, which worked fine, but getting a code up front would have saved a lot of hassle.
Second is the bed. The mattress is one of the modern ones that is extra thick and soft. Some may like this, as evidenced by previous comments that the bed was comfortable, but for us it was too soft and did not provide the back support we like. Also, the bed was made without a top sheet. Again, we are aware that there is a debate about this and some may like it, but we did not.
