For sure, I’ll stay at Hotel Gat Point Charlie again when visiting Berlin! There’s an intimacy to the hotel and soon the staff members will recognize you. Also, they’ll do their utmost to advice/ help you whether it’s to do with renting a bycicle or making reservations at the glass dome. Regardless the other reviews, I could open my windows and just wrote a note to housekeeping to keep the windows open while I was out. Last but not least, downstairs Vietnamese restaurant serves delicious fresh dishes for reasonable prices in a friendly atmosphere.
