This apartment was perfect for our needs. My mom and I visited DC for a week as tourists and used this as our landing pad.
About a half mile walk from the metro, we mostly used the metro in the morning and Ubered home at night.
The apartment was super clean and classy, beds were very comfortable, kitchen was in excellent condition (though we did not cook), and the shower had great water pressure.
Access was really easy with a lockbox.
We did hear upstairs noise during what we would consider "quiet hours" (after 10pm) and could almost make out conversations. After the first night, we used earplugs and slept just fine.
I would definitely stay again if I ever return to DC!
