The apartment was clean, large and in an excellent location for getting around Berlin and hitting all the tourist spots. Check-in was easy and communication prior to check-in was great.
If you're looking for a toddler friendly place - this is not it. The apartment is on the 5th floor and in most of the rooms there are low set windows for toddlers to climb out of. There's no aircon so in summer you'll have to choose between melting or keeping an eagle eye on the child. Also worth noting that because of the awesome location the apartment is extremely noisy at night on the weekends. People partying in and around the building to the wee hours and every door in every apartment (including ours) sounds like an ancient gate to hell when it's opened.. If you don't have a toddler, then no problem.
