I booked this place for my parents during our stay in Istanbul and they really enjoyed it. As a breakdown:
-Neighborhood: It's clean, quiet and safe, located among other rentals. The house is on the 2nd floor, located in an building with a normal slope, not too tiring. At the bottom of the slope there are loads of restaurants for breakfast too, many supermarkets and pharmacies. It is about 5 min from Galata, 4 min from the tramway and buses, and 6 min from the metro. Above the metro, you can find Istiklal street.
-House: The house was clean and had a rustic style to it which was very nice. We used many amenities as the TV, washer, hangers, kitchen utensils. The host was kind enough to leave toilet paper, laundry detergent, salt, pepper, water.... which are all highly appreciated. The only missing plus was the addition of a closed wardrobe and a full length mirror.
-Host: Eyp was very kind and professional. He took the flight itinerary and names of the guests for the shuttle which was organized and punctual. He welcomed us and was flexible and compliant with our needs. We really appreciated everything, thank you!
I highly recommend this place for a true Turkish, care-free experience.
