Pillow is too soft.
Room seems to be clean, but with a smell (as some comments say), not a smelly smell, but sth. in the air.
Elevator is old and seems dirty.
Breakfast is 8.4 EUR per person, all you can get is: boiled egg (boil by yourself), mini croissant, mini another thing similar as croissant, baguette, jam, yogurt, cornflakes, then coffee, juice, water. No scrambled egg or ham. There's a fruit basket, I saw the orange with white mold. It doesn't worth 8.4 EUR.
Mattress is firm, I like it.
I am not sure about the sound isolation, but we do have a very quiet stay.
Room seems to be new and clean.
Private parking is 12 EUR. We arrived after 8pm, lot of public parking available, but next morning was nearly impossible.
