Great location, really spacious and nice apartment. You could sleep 4 here, but don't expect much privacy, as the space is a loft, and the master bedroom upstairs overlooks the living room area below, and can be blocked off only with a curtain. For a couple's retreat, it's ideal.
Check-in was fast, and we got a city map with an explanation how best to get around. There were some crackers and jams with coffee and juice in the fridge for us for breakfast.
The only negative thing was the neighbours were renovating, and whilst it had little to no impact during our stay over the weekend, our last morning on Monday it was very disrupting. It almost sounded like they were about to drill through the wall and into the upstairs bathroom. So if you're staying over during the week, check if the renovations next door have been completed or not.
