Jibhi of Tirthan valley is a hamlet full of greenery, which gives a traveller relaxed atmosphere. There are a few workations you could check. My good trip offers a good package
There is a workation in Banjar
Treehouse workation in Tandi. Besides you can look into homestays too.
Well jibhi is a great place but for workstationyou should try sainj valley or shangarh , because its a village wiyh no crowd at all and internet good and packages are low and beautiful place to visits
