Last year I blogged about vacationing in Scotland and running a bookstore for a week (http://schatjesshelves.blogspot.ca/2016/02/a-bookshop-holiday.html).
Here’s another suggestion: staying in a library in Wales. “Gladstone’s is the only residential library in the United Kingdom, offering a selection of 26 boutique bedrooms with en-suite facilities, as well as housing a unique collection of over 250,000 printed items. Guests staying at the library have extended use of the reading rooms from 9am to 10pm after doors close to the general public at 5pm, and library books can be taken to bedrooms. Rooms have Wi-Fi access, tea and coffee making facilities and radios. In order to preserve the ethos of study and reflection, none of the bedrooms have TVs, although there is a dedicated television room on the ground floor available for all guests to use” (http://www.lonelyplanet.com/news/2016/12/19/you-can-stay-beautiful-gladstones-library-wales/).
Check out the Gladstone’s Library website at https://www.gladstoneslibrary.org/accommodation/sleeping-with-books.
Reviews by people who have stayed there have certainly been positive: https://www.tripadvisor.ca/Hotel_Review-g804424-d1218514-Reviews-Gladstone_s_Library-Hawarden_Flintshire_North_Wales_Wales.html.
