What a privilege and pleasure to stay with Mark. He has a super professional operation. As an Airbnb Superhost myself, I have very high expectations and standards as a guest, and Mark was really outstanding. He provided all the needed info in advance. His electronic lock prevented the need for a clumsy "key exchange." His home is impeccably remodeled and tastefully decorated. The bed was crazy comfy. The location is fantastic. I really have no complaints at all, and I will look to Mark each time I return to DC. Thanks, mate!
