We booked a Guayaquil day tour including the Historic Park on the My Trip To Ecuador website. Mario responded to the contact form on the website within a few hours. He promptly answered all my questions about shared and private tours he offers and booking and PayPal payment were super easy.
For the tour the SUV he used for 2 of us was clean and comfortable. Mario was on time and explained the day's stops.
Throughout the tour he was informative without being boring or talking too much. He was flexible. For example, since it was just two of us we asked him to take us to a local restaurant of his choosing where the locals go for lunch, he picked a small place that was all we wanted. And later in the afternoon, we wanted to take a short break in the afternoon and enjoy a coffee. No problem at all, and while having a coffee we enjoyed our chat about owning and operating a travel business in a pandemic.
Mario was conversational, informative, easy going, promptly responds to emails, and spoke English well and with ease. It was a great tour. Would definitely recommend.
