Please check on our website in the apartment description if in the flat you book if smoking is permitted.
If your flat is non-smoking, in order to respect your flatmates and people living in the building and possibly hygiene/fire regulations, we kindly ask you to respect it and not to smoke at the window or in the common spaces of your building.
If you are a smoker, we recommend you to ask during your check in to your host where it will be the closest appropriate place to smoke in your building (sometimes you have a smoking courtyard, etc.).
