Our party of 5 stayed here for 6 days in September 2018 and had an amazing time.
The listing says there are 2 bedrooms and 1 pullout sofa in the living room, but I was pleasantly surprised to find that the living room could function like a room -- it had it's own door so whoever was sleeping on that sofa bed can still have their privacy! It was great!
Everything was clean, Viski gave us a brand new pack n play for our 8 month old, and you can't beat the location -- you're right behind the national gallery!
I noticed some other reviewers mentioned the noise at night -- we were in the room away from the streets and heard no noise. So if someone in your party is sensitive to noise, they can take one of the bedrooms that is not facing the main street. The two rooms in the front do get a bit noisier, but it wasn't anything that a white noise machine or ear plugs couldn't fix. I've lived in apartments that were far noisier. You're in the heart of the city, so a little noise is to be expected.
Overall, fantastic place. Will stay at again.
