I stayed for 6 weeks while working nearby and enjoyed the space and the location. The neighborhood was nice and quiet and the Takoma Park Metro Station was a 15 min walk away, making downtown DC accessible. Street parking was always available making it ideal if you're planning on bringing a car. David was kind and quick to respond to text messages.
The only part of my stay that was problematic was the A/C unit was broken for ~4 weeks. Some days were OK with the windows and a fan, some days were not.
