The apartment is only a short walk from Sudstern u-bahn, which means travel around Berlin is very straight forward. On arrival we were advised to call a friend of Daniele E Patrizia who advised us check in time was 1pm as the apartment had to be cleaned after the previous occupants. This was ok with us as we only had to wait 1.5hrs in a local cafe before we could leave off our bags. However I wasn't too happy to learn that check out was 11am on the day we were leaving as it stated very clearly on our itinerary that check-out was flexible. As we had a very late flight from Schonenfeld on our departure day this was not at all helpful; it had been one of the reason I had chosen this property in the first instance.
Another issue was the noise from the residents above - they were very noisy on the Friday night - but it was a Friday night after all. And thankfully it was only the one occasion that we found them noisy.
Truthfully these are the only issues we had. The apartment is cosy, but serves its purpose. The area is nice too - especially around the u-bahn station area with a supermarket only 20 meteres from the u-bahn.
All in all it was a nice place to stay in Berlin.
