High recommendations!
Lakot is a great host, very communicative, highly responsive and polite. The apartment has a great location, close to Istiklal street and Tophane metro station which takes you to Old town(Sultanahmet) in 5 minutes. Neighbourghood is very nice, and safe, I stayed with my mom and we felt very comfortable walking there in the late evening.
All in all, it's a great place and I would recommend it with all my heart!
