My husband and I stayed for three nights on our Honeymoon while also experiencing the stress (and baggage) of moving from Central Asia to the USA. Yusuf's flat is amazingly priced considering that it's located in a boutique hotel in a quiet residential neighborhood located just 5 minutes walk away from Blue Mosque and the Hagia Sophia. My husband and I never needed a taxi unless we were going to the Asian side of the city because the location was so walkable. In the hotel, we took advantage of an in-house massage therapist (who was amazing and charged a very good price!) and the hamam which was included in our stay. It's also worth noting that I didn't realize there wasn't a lift for the flat we booked so the staff (upon seeing that we had most of our earthly possessions with us) upgraded us for free to a flat with lift access. Awesome stay, awesome staff. We'll come back.
