We spent 4 nights in Tevfik's apartment in Istanbul, and would definitely stay there again. The apartment was spacious, clean, comfortable, and well-equipped. The location is great - most of the main tourist attractions of Sultanahmet are walkable, and that was with 2 young children! There are also many reasonably priced places to eat nearby. Tevfik and Neuman were very helpful, and we really enjoyed our first time in Istanbul.
