I had a few misgivings about being in an outer borough of metro DC, but having stayed there alone, I never felt unsafe. Getting to the middle of DC was easy ---I was in the center of the action within 15 minutes, once I took an Uber to the Metro. I could have walked to the Metro but I didn't know how to orient myself. Had I asked Mitu, she would have told me. She is a great communicator! It takes two minutes to get an Uber, even at night, which is how I got to Takoma Station and back to the apartment. I did this multiple times, and it was always very easy. The trains are amazing – they run like clockwork and are clean, like Europe's.
The owner keeps everything very well-stocked. The towels, fragrance-free bath products (nice touch!), kitchen-ware, bedding, etc. are all of high quality and you won't need a thing. There is even a private laundry area (washer and dryer.) She had bottled water for me in the fridge, and the whole house is on a filtration system.
I had friends join me for one night and there's a very big trundle bed in the main studio living area. The apartment is shaped so that there is a long hallway between the bedroom and the studio area, so you have a lot of privacy. I would definitely recommend this place for an extended stay – if you are looking to save money on housing, this is a great value.
