Amazing location, incredibly convenient for getting to the Hagia Sophia, Topkapi Palace, and anything in Sultanahmet. The closest tram stop is only about 4-5 minutes away as well.
Responsive and helpful host, and good quality flat in general, at a good price.
We all had a great time visiting Istanbul, and this well equipped flat certainly contributed to our enjoyment.
We've given 4 stars mainly because there is a small leak in the bathroom, which I believe should be fixed, and some other minor things I won't bore you with.
I would happily stay again.
