This is a great spot from which to explore Istanbul, and is right in the centre of a variety of restaurants, bars, and cafes. It’s also very easy to get across into the main tourist areas to see the sights.
Check in at the apartment is particularly easy, and there are always staff waiting to help out at the front desk. The apartment itself is modern and comfortable, with all necessary equipment. As other reviews have mentioned, it is noisy as other apartments in the block and the nearby prayer calls can be heard fairly loudly. But would definitely recommend as a very cool and good-value place to stay in Istanbul!
