Experience
Guest-Rm
Guest-Rm (pronounced "guest room") presents a new way to host friends and family.
The website offers users the possibility to build a trusted network of friends so they can reserve each other's homes, with the unique feature of having a one-time fee of $20 per reservation, no matter the number of guests and of nights they stay.
Together with the Toptal designer, Csaba Házi, we went back to the drawing board and completely redesigned and redeveloped this existing website with many more features and a better user experience.
