My stay at B1 Hotel in Sofia was disappointing. The room was unbearably warm, and the air conditioning didn’t work—reception simply told me to open a window, but the hotel is in a noisy area, making sleep impossible. Thin walls and an adjoining room door meant I could hear every conversation next door. The bed and pillows were uncomfortable, the shower constantly dripped, and there was no lock on the door. While the decor was nice, the location was convenient, and the shower had good pressure, the lack of comfort and amenities made for a frustrating stay. Wouldn’t stay here again.
