We stayed at Yusufs places for two nights. Yusuf and his team were really hospitable and keen to share their knowlege of Istanbul. They gave us a some great tips and were super friendly. The building and rooms are quite modern and stylish and the building is in a great location (very handy to the Blue Mosque and other key sites). The only negatives for us were in the room itself, the linen and towels had been cleaned but a few stains and rips suggest they should be replaced. They kitchen was pretty limited in basic supplies (no oil, plug for the sink, tea towels, cloths). We were also given a different room to the one in the photos, not a problem for us but just to note. Overall we did enjoy our stay at Yusufs and would recommend it to others!
