Trudy's place is in a great location, it is only a couple of minutes walk from Bernauer St. underground station. There are plenty of good restaurants within walking distance. The apartment has everything you need for a short stay in Berlin. The check- in is a bit complicated; despite someone calling me to ask my ETA, I still had to call back again an hour before my arrival. It is also worth noting there is a hefty €30 fee for checking in after 9pm. Still a great place though.
