Sonja place is very clean, very bright, it provides mini kitchen, refrigerator, dishes, very good stereo speakers :), bed is coasy, fresh towels do await. It is just a perfect place few minutes walking distance away from Westbahnhof and additional few minutes walking distance away from Wiener Stadthalle. Sonja is very friendly. We had no problems with our early check in and also no problems checking out. Would love to come back again! Thank you!
