We stayed at Erhan's spacious, clean, DESIGNER apartment for 7 days. He was a great host. He gave us a lot of useful information about the city of Istanbul. He occasionally sent me text messages to see if we needed anything, which was nice.
The apartment is on the 3rd floor of an old building without an elevator. It was nice for us to go up and down the stairs getting a quick workout. There is a mosque only one minute away. Galata tower and its neighborhood is a few minute walk, climbing up a steep hill. So, for those who want to do mild to moderate exercises while in Istanbul, this apartment is the perfect place.
There is a large container of drinking water in the kitchen. We had two deliveries during our 7 day stay. It was delivered to the kitchen within 30 minutes of the requested time. We paid 13 Liras cash for one container to the delivery person. Price was as of January 2019.
WiFi connection was very good. We sometimes had 3 devices on at the same time, without any connection issues. I charged power bank and devices (from US), using the USB on the plug that came with a portable pocket wifi I rented in Istanbul.
Overall, we were very happy with the host and the apartment. We felt HOME.
