This place was all it said it would be and more! We found the access to central and cultural Berlin to be much easier than imagined, via U-bahn and S-bahn. Walking locally was also much more interesting than expected and we had some good meals close by (at Mio in Samariterstrasse for example). Cafe Sybille on Frankfurter Allee was a great choice for a long catch-up with a friend over coffee. Other buildings of the 60s and 70s along this monumental boulevard sparked our interest. And the little shops here and there in Friedrichshain also fascinated.
Arriving in Berlin by train, we found the apartment easily (a short walk from Samariterstrasse station on the U-bahn, line 5) - but watch out for the speedy cyclists on the footpath, especially as you step out from the station onto Frankfurter Allee! The connection back to Tegel Airport worked smoothly too, by U-bahn to Alexanderplatz and airport bus from there, even setting off at 4am.
We stayed for a week and we really appreciated coming back to the apartment day after day. The spaces are well used and they stood up to repeated tests. All amenities which we wanted were available. And there was a generous stock of basic food and household supplies.
Apostolos was a kind and helpful host who made sure in advance that we were set up for a successful visit. He was available if needed during the week (we enjoyed several conversations as our experiences of Berlin grew). Plus his shop made a good hunting ground for an extra souvenir.
