Lily and I want to thank you again for the wonderful bicycle tour we had with you this past Thursday. We enjoyed the countryside, the windmills and castle and your company. It is obvious that you enjoy your job and we wish you the best of luck.

Thank you very much for your great bike tour in the countryside of the Netherlands. This was absolutely one of the highlights of my tour to Amsterdam. I'd like to thank you also for your pleasant guiding, the beautiful places you've taken us, your great and interesting stories about the places and for the professional organisation of the tour. I'm already looking forward to my next tour with you when I'll visit Amsterdam again.

THANK YOU for the bike tour we made together 3 weeks ago. We are still thinking about the days spent in Amsterdam (especially your bike tour). Thank you very much and good luck for everything in your life.

We did three Let's Go bike and city walking tours; if time had permitted we'd mostly likely have done them all. The tours were punctual and very well organized yet Frederik, our guide, made them seem casual, friendly, and almost ad hoc.

My bike trip to Windmills and Castle was one of the most exciting things that happened to me in Holland. And my special and warm thanks to the guide of our group Frederik. I have not been cycling for years and he was so kind to me not to mention his professionalism. Wish you all the best, Frederik!

Just wanted to let you know how much Dee and I enjoyed both the bike tour and the walking tour last week. You do a great job, of course having a beautiful country and city doesn't hurt either. We will highly recommend both tours to anyone we know heading your way. Again, thanks for the two wonderful tours!

We willen je bedanken voor de ontzettend leuke Mystery Tour. Iedereen was erg enthousiast en vond de door ons georganiseerde dag naar Amsterdam het leukst van de hele week. We zullen het iedereen aanraden die ooit naar Amsterdam gaat.

This is Natsuko from Japan, who joined your Castle and Mystery Tour last week. I'd like to thank you again for your guide and hospitality. I'm sorry I couldn't join your Edam tour. My legs ached the next day. Please take good care of yourself. Bye!

This is just a brief thank you, to let you know how much we enjoyed your cycle tour through the countryside. The nicest part of my stay in Holland was visiting the countryside by bicycle. I hope you have a wonderful season. Kind regards and thank you for your hospitality.

Just a quick note of thanks. My daughter and I really enjoyed our bike trip with you through the tulip fields and to the sea. The video pictures I took, will bring back beautiful memories for many years to come. You did a wonderful job. Thanks again for everything.

Shame on me for writing so late, but it took me for ever to sort through my pictures and other souvenirs. I recommended you to a guide book and take the opportunity to say MERCI again for the 2 very enjoyable tours. I will always keep excellent memories of my trip thanks to you.

We took your Mystery Tour in Amsterdam about 2 months ago and had a great time! We told you that a very big newspaper in Israel wrote about you and we promised to send you the article. In English it states in short: "a very special and great way to find out hidden spots in the capital of Holland, is by a nice guide, who will lead you in an orbit called "the Mystery Tour". The guide will tell you surprising secrets about this beautiful city, which you miss if you don't join!"

It has been 2 months ago since we (my sister, my cousin and me) joined the bike tour and I have spent so much time without writing you, cause this is my first year in University and I am so busy! I miss so much the days I spend in Holland, I love this place!

I went on your Edam+Volendam bike tour last week and had a super time! This day in beautiful North Holland countryside was one of the highlights of my European trip that also included Paris. Again, thank you for a delightful day. It was truly memorable and I will recommend your tours to anyone I know who 'll be visiting Amsterdam.

We had a great time on your tour a couple of weeks ago and emailed a letter to several guidebooks about the excellent bike tour experience with "LET'S GO". We hope to visit Holland again and would love to do another tour! Take care.

I had a wonderful time on your Castle+Windmills bike tour and have sent recommendations to tourbooks via email. If I return to Amsterdam I will definitely take another tour again! I am still intrigued with Amsterdam and the Netherlands and the tour I took with you was one of the best parts of the trip. Thanks again!
