The unit was very clean and as depicted in the photos. We found the location convenient - we were able to walk to the places we wanted to go). Everything worked in the unit, and nothing was missing in terms of toiletries, etc.
The master bedroom has a nice en suite bathroom. The second bedroom is down a few stairs (I believe this is depicted in the photos on airbnb.com) and has an en suite shower and sink (the washing machine is in the same room). The toilet for that bedroom is in a tiny little room at the top of those stairs, outside the bedroom door.
As others have noted, there is a good bit of street noise given the unit's location facing onto a large street. I needed earplugs to sleep well, but am a fairly light sleeper.
Sweet Inn, which manages the unit, was a little late picking us up at the train station (a separate service you can arrange for a fee) and then meeting us at the unit when the driver got us there, but only 10-15 minutes in each case. The Sweet Inn office responded reasonably quickly to a question we had during our stay.
Overall we thought it was a good unit.
