Melody was very helpful and very responsive. She assisted us step by step even when we had a hiccup using the app to open and close the digital locks. Just a heads up that if you are traveling from another country and you have an app store from your region it may not let you download the Chrip App. However, Melody helped us be able to get in remotely.
Only other suggestion would be having some more bath towels. Overall very happy with the experience. The apartment is in a great neighborhood with great restaurants nearby.
