The place is nicely located, just a couple of minutes walk up to the Sultanahmet square and Topkapi castle with nice places to eat just near. You will be able to quickly get to other parts of the city by Marmaray, metro or tram.
Kaya is a very friendly host, he quickly replied to any our requests and addressed our concerns.
The place is rather small, it has everything you might need. At the same time it needs some fixing and cleaning.
