We had two tours with Explorenique: Khlong Lad Mayom Floating Tour and Tuk Tuk Sunset Night Light Tour, and were extremely satisfied with both.
It was our first time in Bangkok and our guide Geng helped us to not only find some hidden locations and see things that most tourists never experience, but also to learn a lot about the history of Bangkok and Thailand. He told us all the secrets and interesting details about the places we visited and also gave us some tips and inspiration on how to spend the rest od our visit. During all this we had some of the best local food, and lots of it, so don't eat before you take the tour :)
Both tours were fun and dynamic, but also friendly and relaxed, so you don't really have a feeling like you are on a guided tour but rather like having a day out with a friend.
Would definitely recommend to anyone!
