I really enjoyed my stay at Ozlem's place. The building is in the historical part of Istanbul, and like most buildings there, quite old - with all the pros and cons that come with age (creaky at the seams but lots of character). I got a loft room - the ceiling was a bit low for my 6'3'' frame, but on the whole, very cozy and clean. There's also an amazing rooftop terrace with a great sea view. The best thing about this place though is the location - really hard to beat, all the historical sights one might wish to see in Istanbul are within easy walking distance. In fact, you can see the Blue Mosque from the rooftop terrace, it's literally a 5-min walk away. Hagia Sophia is a 10 minute-walk, the Grand Bazaar 20 min, or two tram stops. The hosts were very welcoming, and I didn't have any trouble at all with communication, check-in, or check-out. Highly recommended.
