I had a great stay with my parents and baby. It's a great flat for a family with babies or young children because you can stop in for a rest in the afternoon and the back rooms are quiet for sleeping even in such a central location. The front room is also great for people watching from the comfort of your own place!
We did struggle with water pressure, hot water and the shower fixtures, as other guests have noted as well.
Overall, it was as described, and if you're accustomed to old city flats, there will be no surprises. Michael and Oliver were excellent and even brought us a new baby cot within minutes when we discovered the existing one was broken when we arrived. We also enjoyed the coffee and chocolate provided!!
