The apartment is in a great neighborhood, is cute, and isn't too horribly overpriced. If it weren't for a few key issues, I would give it 5 stars without a second thought. The first surprise came about 10 days before our visit, when I received an email instructing me to register with a different company, Hostnfly - which required uploading a personal ID. Look them up if you want to see their abysmal reviews.
Then there was the issue of picking up the keys. We had to go to a separate location - laundromat a 7 minute walk away from the apartment, not at all far. Unfortunately, the code they gave me for the key locker didn't work, and we were left standing on the street with our luggage for an hour and a half.
The apartment itself was great! Though, it was clearly a lived in space - the closets were all zip tied shut and clearly filled with someone's stuff, and there were tchotchkies covering literally almost every surface. Even the back of the sofa had things balanced on it. However, it did feel like you had an actual apartment rented. Location was excellent - close enough to several different metro lines, and in that perfect position where you're within 20-40 minutes of all the main things to do, but far enough away that it's not very touristy.
Overall, the actual space was good, but the experience of important information being withheld until it was too late to reasonably change locations left a bitter feeling. Until the host makes it clear up front that you will have to register personal information to a 4th party, I cannot recommend staying here.
