The check-in / check-out process is unclear and problematic in a few ways. I did not receive check-in instructions until the morning of my arrival and had to prompt my host to get them. I was given no information to indicate that I was to pick up (and drop off) the keys in a GROCERY STORE two blocks away from the rental. OnPoint gave me an access code that did not work, so I had to call for another one. The grocery store clerk who finally gave me the keys had no idea where my rental was located. So, I had to reply on Google maps instead of my host to get me to my rental. Imagine what this is all like for someone like me coming from another country. Imagine what it would be like if someone who may not have an international smart phone plan, or if their phone was low on power. The rental flat itself was beautiful, but there are numerous entry / exit issues for someone with mobility issues. Finally, having to drop the keys back at the grocery store was a problem because we had an early flight and an Uber. Having to walk the keys back over to the grocery store at 4:00 a.m. is not ideal.
