I rented the place for a team retreat for 10 colleagues, and it worked out perfectly for us. Faya was flexible with the timing of check-in and out to accommodate our group and was happy to answer all of our questions leading up to our stay. The location is perfect - just steps from M St. and a quick cab for those of our group who were arriving to DCA. There were plenty of beds and extra mattresses for those of us who stayed overnight. The dining room table and living room couches worked well for us to have our meetings during the day.
One thing to note is that street parking is limited to two hours during the day, and the parking lot across the street is extremely easy to access but expensive for an overnight stay ($12 overnight plus $20 per day). Faya was able to get us a parking pass for one car, which was really helpful . I'd recommend using public transport and taxis rather than trying to park if possible.
Faya went out of his way to accommodate our needs, and even left us some snacks and treats to kick off our stay! I highly recommend staying here!
