We were looking for a place to host my family (my wife, 2 children, 2 grannies and my children's aunt).
Eyüp's place had more than enough beds to host everybody. Moreover, it had two mattresses so we could host even more people.
Also, everything listed in the ad was in place and was working. We could cook for our whole company and eat it all together at the same table.
Another thing, is that the location is really great. The Sultanahmet is extremely close.
One more advantage, that Eyüp told us about main attractions and we checked almost all of them and enjoyed his restaurant and cafe recommendations as well.
On the other side, two things could be improved:
1. Exact location (point) at AirBNB. We arrived and had to call to Eyüp in order to get to the place (~3 mins walking).
2. Eyüp is very slowly responds to messages in app. However, he responds to calls.
Overall, I believe it's one of the best place to host families or big companies at this area.
