Maria and Dan are very welcoming hosts, and are most prompt and helpful in responding to requests. We found the unit very clean and comfortable; and it was well located for access to Bethesda and Chevy Chase, which were the places of importance to us. It is equally well located for NW Washington DC. The unit itself is the basement of their house - and while it fully met the needs of our short 4 day stay, we were concerned that our noises may have travelled upstairs to them.
