Pretty great! The elevator to the third floor is a bit scary, but it's not a huge deal :) Personnel is on site till midnight, so if you're arriving late it shouldn't be a problem to check in - everybody was very welcoming, responsive to our needs, leaving the luggage before/after stay is no problem - highly recommend!
The only downside I can think of is that not everybody at the reception is good at English, so be prepared that you may need to use a translator - but I don't think that's a big deal.
