First time visiting tunnels - Great tour and tour guide Diana was great. We have lived in Houston 3 years and first time visiting the tunnels. Now I understand why we do not see many people walking outside downtown, all the employees are underground.

A Must-Do Tour — Diana Was Incredible! - ⭐️⭐️⭐️⭐️⭐️ Outstanding Tour with an Incredible Guide! This tour was such a fantastic experience, and Diana truly made it exceptional. She is incredibly knowledgeable, engaging, and passionate about Houston’s history. We learned so much—from fascinating stories about the buildings and tunnels to insights we never would have picked up on our own. Diana has a wonderful way of bringing history to life while keeping the tour fun, relaxed, and easy to follow. She was thoughtful about pacing, answered questions with depth and enthusiasm, and made everyone feel welcome and included. If you’re considering the Astroville Tunnel Tour, I can’t recommend it enough—and if you’re lucky enough to get Diana as your guide, you’re in for a real treat. This was easily one of the highlights of our time in downtown Houston!

Interesting. - The tour was interesting. So much history. I've lived 90 min from Houston and didn't even know tunnels existed until a few years ago. Diana was our tour guide. She was GREAT!!! The tour doesn't just give history about the tunnels but also the buildings you're walking under.

Great time Learning about this history of Houston - We had a great guide Diana. There was a lot of history of the city on the tour if you enjoy that kind of stuff. You get to see some amazing architecture and the story behind a lot of the buildings downtown.

Consumer fraud - Daikin Air Conditioner has lowered its quality, both in appliances, installation and customer service. In a month and a half, I haven't been called in to fix a breakdown, plus warranty. Despite being a very expensive product. Unfortunate
