I haven't really seen any detailed reviews of zenhotels.com, so I wanted to share a bit I found about using them..
So about a month ago I booked a hotel through the site, to the La Tomatina festival in Spain. I ended up paying about 30% less on zenhotels for a hotel in Bunol than on other sites I looked at. I booked two rooms (travelling with friends) and this is where we had a bit of an issue - you can't book two rooms at once, you need to make two different reservations. So, I did that, got the vouchers, everything was fine, until I decided to check our reservation with the hotel directly...
I found some negative reviews so decided to check the bookings directly with the hotel. The manager confirmed one booking but couldn't see the second one. We contacted zenhotels customer care through Facebook and got told that our bookings were made through different providers, and this caused the problem. They said they would look into it for us, and confirm the booking again with the hotel.
So we were waiting four or five days for a definite answer, but the team kept us updated every day.
They did apologise for the delay and explained they were waiting for their partner's reply, but they finally got back to us to confirm both bookings, and they gave us a promo code for our next booking as an apology for the hassle.
All in, pros and cons:
+ pretty decent prices.
+ the support is great – the team are really friendly and helpful.
+ even small problems get sorted.
- you can't book two rooms at once.
- if your check-in is a few months away, the hotel might not be able to see your order in their system.
- sometimes you need to push a little to get answers in a hurry (same could be said about any company really though, I guess)
A few smalls cons, but nothing too major.
I'm going to give the hotel a call again closer to the date, just to double check everything and I'll update here.
