It’s a very nice flat, near Taxim square. Very good location - you can reach all interesting places in Beyoğlu on foot. Public transport is also available, 1 min to metro, and about 8-10 to tram.
Very clean and spacious, with 2 balcony.
Elif is a great host, she was very helpful, even in the unusual situation (we forgot keys inside ones).
Take into account that there is no elevator in the building. There is a club near, so it could be noisy in one of the bedrooms, but for us it wasn’t a problem, closed window can solve a problem.
