For context I'm from the United States: Absolutely superb stay. The apartment was a very comfortable size. Kitchen was very usable and came with the necessary appliances/utensils/etc. On-site laundry was easy to get to and use. (*Easy if you're European. Read up on condensing dryers before you go expecting your clothes to dry in 45mins!) Bathroom was spacious with quality fixtures and craftsmanship. The bed was very comfortable. However, the mattress was pushed up against one of the walls. Not a big deal, but if you use a CPAP machine it could be a pain. The TV was great because they a Netflix account built-in. Awesome for those days when you just want to chill. Only real negative was the lack of an elevator in our unit.
Best of all was the location. I don't know how it could be better. It's very close to the metro/trains/buses, but not by a busy street. Also, in the same block there is a grocery store, 7-11, home goods store, etc. Plus, there are a ton of great attractions nearby.
