Our stay at Leo and Diana's in Columbia Heights was very enjoyable. Communication with our hosts was prompt and the check-in process was easy. The ground-floor studio apartment was clean, modern, comfortable, and thoughtfully appointed. It had everything we needed, plus a few extra features that we appreciated. The location was convenient. We used the Route 70 or 79 buses to travel to and from the National Mall, with the bus stop less than two blocks from the apartment. The only area of concern that we want to mention to potential guests is that light sleepers may be affected by the HVAC system that is located in the closet adjacent to the bed; we were not bothered by this, but understand how others could be. In all, we very much enjoyed our stay and would consider Leo and Diana's apartment for a future visit.
