Choosing a place to practise

An original information table for an invented music centre.

The following rooms can be booked for individual practice. The listed features apply to the rooms, not to equipment that users may bring themselves.

All three rooms have a music stand. Headphones can be borrowed at reception, but no room contains a recording system. Bookings begin on the hour. The centre asks users to leave five minutes before the end of a session so that the room can be prepared for the next person.

Identify the room with a piano and a window, and state its maximum session length.
