We stayed in the apartment for a week during our trip to Istanbul. The location was great, close to shops, restaurants, supermarkets and public transport. Being in the centre, it was a great hub to visit all the main tourist attractions. The apartment was clean, had all amenities and was great overall. Abdulaziz was a great responsive host answering questions that we had promptly. The wifi connection could have been better as it kept dropping frequently and was not well accessible from the bedrooms.
Other than this small issue, I would thoroughly recommend this place to anyone who visits Istanbul.
