We stayed at the Diamond Apartment for 3 nights. As stated in the other reviews, it is the perfect location being both quiet away from the noise and bussle, yet within a short walk to Istiklal Cad, Tunel, Karakoy Tram and Ferry, Galata Tower, etc. It is close to Pera Palace & Radisson Blu hotels. A short 10 mins ride on the tram and you are in Sultanahmet where Ayia Sofia and Mosque, Spice Market.. The Diamond apartment has everything required for a short break. It is clean, well equipped and even whilst on holiday, the host Hatice kept in touch to ensure everything was OK, and dealt with our transfers. I will recommend to friends and family.
