Martin is a very good host, he always responded promptly and accurately. He's description of the apartment is accurate. The apartment is well-located in Berlin. The apartment itself is quite modest, but absolutely clean and functional when you know what to expect. Modest cooking is possible, but the kitchenette is more for preparing breakfast and sandwiches in the evening. If it happens to be hot in Berlin for a longer period, the evening sun may make the apartment quite hot, for us it was now OK. The apartment is on the ground level. Therefore if you want to have daylight with open curtains, passers-by might have a glimpse at your activities.
