My girlfriend and I chose Deb's place when going to DC for her birthday. We enjoyed our one-night stay at the Merhaba House. The check-in process was a breeze and Deb gave us a little tour when we arrived. The place is a nice and comfy spot for a couple and potentially one or two more people (there's a couch and extra blankets). It was in a great location for us during our short stay. As far as the place itself: The air conditioner worked well when we needed it and the kitchen and bathroom were nice and clean. The office desk was useful when I needed to do a little bit of work. There's free WiFi - which was pretty fast for our use, as well as a Roku TV for streaming needs when you're relaxing.
Deb was very sweet and friendly - she even gave us some recommendations for oysters places nearby (my gf LOVES oysters). We have no problem recommending Deb and her place to others.
