I stayed at Diana's place for 5 days, and honestly, it couldn't have been better, it ticked ALL my boxes. It's clean, perfectly located to Capitol Hill and an easy walk to Congress/historical areas. The location is safe, I travelled solo and felt safe at all times, good lighting system and the place felt secure, as well as the neighbourhood feeling safe to walk in at any time of day.
The unit comes with everything you need, and then some. I didn't need anything additional, it was so nice to have everything in one. The bed was incredibly comfortable and it was fantastic that the TV spins so you can watch it in the lounge area or in bed. I'm not super technical with TV apps and I found it easy to use - movies, news, a guide, it's all there, on a good sized TV, for the times you're in the apartment.
There's a full kitchen, cooker and micro if you want to cook, which I did, and also a washing machine anddryer, very easy to use, which is incredibly useful if you need to wash a bundle whilst away. After a long day of sightseeing, it was a delight to come back to the apartment to relax.
I'll mention this as others have commented, but to be clear, yes, you can *sometimes* hear the pattern patter of feet above - however, it is in no way intrusive, nor for prolonged periods, nor does it wake you nor keep you from sleeping. I'm both a light sleeper, and deep sleeper, depending on the day I've had and I had a GREAT night's sleep. Also remember you are in a period home, for 100 years old, you may hear a few steps above, but as per previous it's not a problem in any way. Additionally, I was out of the unit for most of the daytime so a few mins of hearing a few footsteps really isn't an issue. I loved the air con, which was much welcomed as the temp outside hovered at around 85 degrees, the apartment was perfect temperature controlled. There's a shower with beautiful shampoo and conditioner, which was just delightful.
All in all, I thoroughly enjoyed my stay at Diana's, I wouldn't hesitate to recommend this unit, great value for money, in a good area, grocery shops and restaurants are less than a 5 minute walk away, safe and secure, and good communication with Diana. a solid 10/10 from me - I was actually quite sad to leave!
