Alex is a excellent host. Very communicative and friendly. He answered us very quickly. Help us with tips of the neighborhood and booked us a private transfer to the train station because we had a lot of difficulties to get a taxi with all the luggage and the two babies that were with us. The apartament is very nice. Big, comfortable and has everything you need. Is in a nice and quiet courtyard. The heating works perfectly and the bonus for us was the shutters all over the big windows that provide total darkness to have a good night of sleep. We were with two babies and Alex provide two baby cribs for them which was a nice gesture because we booked the apartament without that and he bought it for them. The kitchen is well equipped and has the basic for a standard meal. The bathroom has a bath and a separate shower (big shower that stays above the head different of the regular german shower). One bedroom has a nice queen bed (1.60x2.00) and the other a double bed (1.40x2.00). The smaller bed was a little bit noisy but it was not a problem at all. The dinning room has comfortable chairs and sofas. It is 5min walking to the U Bahnhof Schlesisches Tor. Easy connection to the city center. It is a 18min walking from the train station Berlin Ostbahnhof. Has good options of markets and bio markets (Bio company) close to the apartment. Burgermeister is a really nice burger near the apartment. I higly recommend Alex place and I hope to stay here again.
