Cute art deco hotel. If you're looking for an affordable hotel I would recommend this one. PROS: near subway and grocery, clean, nice breakfast, quiet rooms- walls are not paper thin like a lot of European hotels, you can leave your bags at the front desk after checkout if you want to explore the rest of the day before your flight, staff was very nice.
CONS- their idea of airport transfer is calling a taxi for you. It costs €55. They will not answer the phone if you try to call before your stay. You need a passcode to get in after hours but they don't tell you that when you check in. All the hallways smelled like cigarette smoke, however, my room did not smell like smoke The mattress was pretty hard. I never like carpet in rooms because you never know how dirty it really is.
I stayed at a time of year when I didn't need heating or air conditioning, so I really can't say anything about those either way.
