I am not exaggerating when I say that this is probably one of the best places to stay at in all of Istanbul. For starters, the location is unbeatable. Furkan's apartment is located less than five minutes away from the Galata Tower, a beautiful building that also functions as a useful landmark for cab drivers when traveling by taxi. There are several excellent restaurants and a market nearby that served all of our needs during our stay. If the metro is your preferred method of travel, the closest station is less than ten minutes by foot.
The apartment itself is gorgeous. My family of four was pleasantly surprised by how large it is, and we found there was ample space for everyone. The kitchen is fully equipped and the washer/dryer was a lifesaver. We also enjoyed having a full as well as a half bathroom, as that made getting ready in the morning much easier. The patio off of the living room is a pleasant place to drink a coffee in the morning as the sun is just rising or to relax in the afternoon between tours and dinner.
There is one flight of stairs to get to the apartment, but it is not a challenge. My grandmother, who recently hurt her foot, was able to go up and down the stairs without much of an issue, so I would say this place is definitely accessible for all age ranges.
We were extremely pleased with the quality of our stay at Furkan's place. I would wholeheartedly recommend it to anyone.
