I've always been familiar with Beyoğlu and Tunel area since many years back, so this location is of my choice definitely. It's very near to Tunel funicular, the Sishane metro, so for transportation consideration, this is excellent. It is in a quiet lane but just so near to restaurants, bars, mini markets and more. Lots of life to discover around here. The apartment is spotlessly clean, and we've had very comfy and quiet stay.
There were some reviews saying there might be night life noises around weekend, but fortunately for us there were none.
Well done! Definitely worthwhile and no complains!
