As others have mentioned, this apartment is in an absolutely fantastic location. We exclusively used public transportation and could get everywhere we needed very quickly with the metro right outside the door. There are two grocery stores a block away and the neighborhood is nice and yet not overly crowded with tourists. It was great to be able to return home from the crowds and relax. The apartment is clean and would be great for up to 6 or 7 adults. Wifi was great, and was reliable enough to use it to work as needed through our trip.
There were only two downsides - the first is that the check in location is quite a ways from the apartment, which can be difficult if, like us, you are arriving late with bags and children. The process delayed us quite a bit. That being said, this detail was included in the listing so we knew to expect it. The second was that, even though the listing said there would be cleaning service every 4 days, nobody came to clean anything during the 14 days we were there. We messaged the host and eventually someone came to take out the trash (which we had already done multiple time) by day 10, but that was all. So we had to clean as well as re-stock essentials like toilet paper, dish and laundry soap, etc. We often have to do this on longer trips, but again, the listing mentioned cleaning and there was none.
