Beware of Vivastay, they have poor cancellation policies and even worse customer service. I booked with Vivastay and needed to cancel. Their cancellation policy states a minimum of one night. One night is standard in the hotel industry. However, they charged me 2 of the 3 nights I booked. They offered no explanation or reason why it was more than the minimum. Even worse, they sent me an email stating that I had 3 hours to respond to accept the 2 nights penalty - or they would charge me for all 3 nights! What if I was away from my computer during this time? I already emailed to cancel the reservation... and they would have charged me all 3 nights. Unbelievable.
After contacting the company, they didn't care one way or the other. They stated in an email to me "understand that we have provided the service you have bought and it is your choice to cancel." I know it is my choice. But why more than the minimum? I imagine just because they want to make money. Good luck with that business model.
Very poor CS - stay away from VivaStay.
