We have stayed at Peter's Central Station Studio 4 guesthouse for one night.
Good.
Very close to mayor transportation and city center.
Private room with oversized shower, all necessities, extras like water/coffee/tea/Netflix. Everything is clean and works well.
Challenging.
During Peter's absence his colleague was helping with checking procedure. Perhaps his limited English created very awkward interaction with several misunderstandings (ID check/picture, check out time, etc)

Overall stay was good and Peter was very good in post-communications and resolution of mis-understandings.
