Taner and Nico are excellent and helpful hosts.
The rooms were exactly as pictured and the location terrific. I would describe it is a being on a local street, and while busy by North American suburban standards, it had a great relaxed feel first thing in the morning and at the end of a busy day - relative to the rest of the places you'll visit. In this and other nearby buildings there were many fellow travelers and I felt safe at all times.
The floors and ceilings are thin and on a couple of evenings noisy neighbours above and below me were distracting.
This was my first visit to Istanbul and I recommend this location as a great place to set up base and explore the city. Have fun!
