More than a 4 stars it's probably a 3 stars. Noisy, for both bad sound isolation and noisy room doors. Breakfast was decent but nothing more (some fruits have been offered for three days in line). Rooms cleaning was an optional: I've asked every day to clean below the bedroom and everyday they didn't! It is simply overpriced for what they offer!
Very clean and every thing you needed for a stay
The restaurant was badly organised.
