We had a great stay at Tevfik's apartment. On our first day I asked him if you could possibly check in at 10 am and he said yes we can. I meet Tevfik's cousin he showed us around and gave us Istanbul map with some tips and suggestions. The apartment has a two decent sized bedrooms,kitchen and bathroom there were clean towels and sheets almost every day, it was about 10-15 min walk from sultanahmet area. Unfortunately on our last 2 days my friends got sick so I asked Tevfik if we can check out late on our last day because we had a late flight and he was so cooperative . Highly recommended and I'll definitely stay there again
