Apartment is small but well-designed, with good facilities and comfy bed and couch. Quiet area, and even gets a little sunlight during midday. The neighborhood isn't very exciting, but the center is a short metro ride away.
Service is so-so. Check-in was a half-hour late, because they were still cleaning, and they didn't tell me it would be. I had to wait outside the apartment with all my things. Still, the fridge had a terrible rotting smell afterwards, and I avoided opening it as much as I could. Also, I was there for a week but only given enough amenities for a weekend, and they insisted they "don't provide the service" of giving more.
One more detail - you won't get a key to your room; you'll enter with a code. So there's no way for you to lock the door at night, or at all.
Overall, it's a nice place to stay.
