Guest reviews, in their own words

“I had an amazing experience with this yacht tour company. They are truly professional, and the service was excellent from beginning to end. A special shout‑out to Alpe — he explained everything clearly, was very attentive, and made the whole tour even better. I highly recommend this company to anyone looking for a smooth, enjoyable, and well‑organized yacht experience.”

“The boat was very comfortable, and there were plenty of drinks and fresh fruit served throughout the trip. The tour itself was excellent, and we really enjoyed the company of the tour guides, especially Mert, Alper, and Ceylin. They were friendly, welcoming, and made the experience even more enjoyable. We had a great time and would recommend this tour.”

“The sunset tour was a great experience! The hosts provided good context to the history of Istanbul. They were very friendly, offered to take different pictures for all families. They provided light snacks (i.e., roasted peanuts, biscuits and cherries) and beverages. Overall, it was awesome! Would definitely recommend”

How these reviews are collected

Reviews are left by guests directly on Google, Viator and GetYourGuide after their cruise. Each platform verifies the account, publishes the review under the guest’s name and shows it in full, including the ones that are critical. We reply to every review, and when something has gone wrong we say so in the reply rather than asking for the review to be removed. On our own pages we quote reviews only with a name, a platform and a date, and we do not add review markup, so search engines take the ratings from the platforms rather than from us.

Most of the reviews are about the daily Sunset Group Tour, because that is the cruise most guests take. Private charters produce fewer public reviews by nature: a company dinner or a proposal is not usually reviewed online. The crew, the yacht and the service they describe are the same on both.

Leave a review

If you have sailed with us, a short review on Google helps other travellers more than anything we could write. Write a Google review (a Google account is needed). If something was not right, please tell us first on WhatsApp; we would rather fix it than read about it.

Frequently Asked Questions

Are the reviews on this page real?

Yes. Every quote was published by a guest under their own name on Google, Viator or GetYourGuide. We reproduce the text unchanged, with a name and the month of publication, and link to the platforms so you can read the full lists, including critical reviews.

How many reviews does Constantine Yachts have?

More than 700 across the three platforms, checked on 28 August 2026: 259 on Google (5.0), 279 and 84 on two Viator listings (4.9 and 5.0) and 96 on GetYourGuide (4.9). The counts grow weekly, so the platform pages are always more current than this one.

Why can I not leave a review on this website?

Because a review on a third-party platform can be verified and cannot be edited by us. Turkish consumer law also requires that published reviews come from real customers, and the platforms enforce that. We link to Google’s review form instead.

Which tour are most reviews about?

The daily Sunset Group Tour from Karaköy, as it is the cruise most guests take. Reviews that mention private charters, birthdays, company dinners and anniversaries are quoted where they exist.
