The Raven is in a brilliant location if you want to make the most of the many bars, restaurants, pubs and clubs in Istanbul. Its close to dozens of great places to eat, drink and shop as well as to lots of transport links to the rest of the city.
The apartment itself is nice and is as pictured in the photos. We didnt have much contact with the host in advance or during the time we were there but they did answer all questions we had quickly and were pleasant to deal with.
The only downside is the noise level from the bar below and from other residents coming in and out as there is pretty much no sound proofing in the apartment. However, we were aware that it was above a bar when we booked - its something to consider if you are planning on having a relaxing evening in Istanbul. We were out and about most of the time so it was fine!
