Good place for one person to stay. The mattress was more comfortable than I expected from a sofa bed (not too soft or too firm), and the bathroom has a very nice sink and shower with good water pressure. Location in Le Marais felt safe and was convenient right next to shops and restaurants. It was not too noisy either. The staircase up to this studio is narrow and there's a pretty big step up into the shower, so you do have to be careful going up and down each of those.
Manon communicated clearly about check-in/out process and responded quickly to questions. Thank you!
