The hosts are really kind and good at communicating, the location is very convenient (relatively short walk to metro, etc.), and the apartment has charming early to mid-20th century features (high ceilings, archways, etc.). The window AC worked well to keep it cool.
Now for the areas of improvement that are needed...
Re: the Check In process... I reserved the apartment on very short notice as my son (in college in Chicago) had emergency surgery. So I made the reservation the night before and they accepted it. I communicated an estimated time that I would arrive at apartment, but really wasn't sure because it depended on when he checked out from hospital, etc. I said 4:00 but ended up being ready earlier (2:00) which is the starting check-in time that was stated in the listing. I messaged them to see if I could get in sooner to drop off all my stuff and was told that they were an hour away and couldn't get there until 4. So I walked around with all my luggage killing time. I got there at four. They arrived around 4:10 to let me in, and then they still had to make the bed and said they would bring towels by later. A few hours later, the towels came, but were still not totally dry from the dryer. So I hung them on the backs of chairs hoping they would dry by morning. All that to say, the check in process wasn't completely smooth. With the caveat of my late notice for reserving, I still wish it had been handled a little differently.
Re: cleanliness... As a couple of other reviewers have mentioned, the apartment needs a lot of decluttering and cleaning. I definitely just used it as a space to sleep and shower and that's it.
