This place is the best value for the money that you will find. Very close to DC, just a short walk to the metro green line, which will take you right into downtown. The street is quiet, with good parking and the door is very easily accessible. I couldn't have felt safer, especially with the security system specifically for the room downstairs.
The bed had a very large memory foam mattress topper, which may be a plus or negative, depending on how you sleep, and there is a mini fridge, toaster oven, and keurig with coffee. The space was very clean with extra blankets everywhere in case you get cold, and the TV and entertainment system was very nice to have something to watch.
Overall, couldn't recommend Rebeca's place enough and we will definitely be staying here again the next time we visit DC.
