This place is in a great location, and Yusuf and Errol are amazing hosts! We had coffee and chatted with Errol in the morning and he gave us great tips on getting around and where to go shopping for certain souvenirs (in our case, rugs). It's so easy to get around to main sites (blue mosque, hagia Sophia, grand bazaar) from here just by walking, and now that the new airport is much farther away, Errol also helped us arrange a taxi when we needed to leave and we were able to keep our bags here while we went out exploring before our flight.
A couple of notes that reflect other reviews: the street is very loud. We arrived in the evening and it was quiet and peaceful, but in the middle of the night there is construction, deliveries, and constant noise. Maybe I'm just not used to a city anymore, and if you are this wouldn't bother you!
The second note is the bed is very uncomfortable and hard. I travel quite a bit in a range of accomodations so I'm used to a variety in sleeping arrangements. Every effort is made to make the small space comfortable and stylish, but the bed was like sleeping on a pallet. For one night, it was fine but I can't imagine staying here longer than that.
Overall we had a good stay and would highly recommend this spot for anyone not bothered by the things I mentioned.
