The place is good place to stay if you're on a budget and need to be in the middle of downtown DC. The convention center metro station is only 2 blocks away. I didn't realize when booking that the apartment was on the opposite end of the main entrance for the convention center so that was a long walk there and back each day but that was more my fault for not knowing the area. If you are going to a convention and it is only using the main entrance (building 1) to allow people in, I would choose a place further south which is closer to the entrance. But my friend and I liked the place. We enjoyed having two bedrooms though the place has a lot of stairs. The neighborhood had lots of activity and people late at night but we never really heard it from inside. Check-in was really simple and easy and the place is easy to find. Make sure you plan ahead for parking though as this place has no parking permit included. There are spots on the street so you can park temporarily to unload/load but we booked parking through an app down in the city center for a lot cheaper than the one near the apartment.
The amenities are good and everything works as it should. There is an iron and ironing board as well as hair dryer even though the listing says they aren't provided. That was definitely convenient. I think the part of the apartment we liked the most was the full mirrored closet doors in each bedroom. They were very useful for getting ready each day since the bathroom mirror was tiny and lighting wasn't ideal. I slept in the back bedroom and the bed was soft and comfortable which was a pleasant surprise. Be aware though that this place has some bugs. Definitely nowhere near an infestation level but it isn't free of the occasional creepy crawlies.
Our host Adrienne was definitely responsive to our messages which helped a lot and we ran into her on the final day. It was overall a pleasant stay.
It's a decent apartment for a decent price. I think I would rent elsewhere, though, if I come back for a convention but that's mostly due to the location and not the apartment quality itself.
