During a trip to Turkey on july, we had Serhat Gonlugur as our guide. About his performance, it was exellent and we did not had any complaint. He speaks portuguese fluentlly and is extremally polite and helpful. Thought the trip, he gave us all information of all the cities we stopped (Istanbul, Bursa, Cappadocia, Pamukkale,etc.), including the whole history of the main historical points as well as curiosities about the local culture and daily life. He was quite friendly and helpful and got fine whit everybody on the group, thus making the trip even better than we we expected. Serhat Gonlugur is a perfect professional and one of the best guides we already had. From Brazil, Leilane, Luiz and André Andreatta.
