Small but well decorated, well-equipped and clean rooms.
Lack of air conditioning makes the room very hot in the summer.
Remote key system (Klevio) is very cumbersome (need to install an app on your phone and create an account using an email address that you must then share with the hosts; cannot get into the room unless you have your (charged) phone with you and have a data connection; digital key not easy to share). A physical key, although advertised, was not possible in my case, at least on the first night.
