I highly recommend staying here. It has great proximity to restaurants, cafes, and convenience stores on H street, as well as bus stops so you can go anywhere else you might like. The neighborhood is quiet and seems as safe as you can expect a neighborhood to be.
The room is a little small but perfectly suitable if you're going to be out most of the day every day anyway. My friend and I comfortably fit a twin sized air mattress at the foot of the bed, so it's not uncomfortably cramped. The hosts also provide plenty of snacks, coffee, and tea as well as some basic toiletries and a few other odds and ends that might be useful for your trip (like umbrellas and bike helmets).
Adam and Jen are great hosts in that they will gladly leave you be the entire time if that's what you want, but also made it clear I could reach out to them if I needed anything. Jen was also conscientious enough to inform me about a positive COVID case in the party that stayed before me. She gave me the option to cancel or reschedule if that's what I preferred, but also let me know the measures she and Adam were taking to sanitize the room before I arrived. I opted to come anyway and it was apparent they made every effort to clean the place from top to bottom.
This place suited my purposes perfectly and I would happily stay here again if I go back to DC.
