The place itself was fine, there is tea/coffee/salep provided as well as a washing machine and dryer on the bottom floor. Check in was straightforward. The only “complaint” is that the bathroom was quite small but overall absolutely worth the price we paid.
There is no lift/elevator but Kalen was kind enough to help us bring our luggage up to the room. Kalen himself is a great host, he gave us a tour of the surrounding area when we arrived and offered a free 2 hour tour of Istanbul itself. We were ill for a couple of days and Kalen contacted us on Airbnb to make sure we were fine and if we needed anything, so really great host.
The location itself is good, it’s close to Haliç metro, bus stops and the ferry terminal (especially important if you want easy access to the Asian side of Istanbul). It has nice cafes and places to eat close by, pharmacy, shops etc. And it is definitely cheaper here than where we stayed in Galata :-)
