The good: Lamar's place was absolutely spotless, close to everything, and a good size for Georgetown. Lamar was very quick with responses.
The bad: the check-in procedure was unnecessarily complicated. One needs to download a special app beforehand. The instructions on how to use the app were unclear. When we arrived, the app ended up not working properly.
Lamar addressed all the issues very quickly though so we were able to check in without much delay.
