Metin and his team booked me an awesome two-day trip to Ephesus. I wanted to see some of the ancient ruins on the day-tour, but also some sites not on the tour, so they set me up with a personal tour the day before. The hotel they set me up in was on the water and in a great city to visit the day before the full-day tour. They have a nice office near the Blue Mosque/Hagia Sophia area so very convenient. Most helpful was that when I was on the trip, they supported me throughout when I had some questions while on the trip via WhatsApp. I worked with a different tour agency to get a Bosphorus tour before I found Before Travel (and it wasn't great) so I realized that Before Travel is the best in Istanbul. Thanks Metin and team!
