It was a good 3-star hotel. Although some common areas have been renovated, the rooms have an old-fashioned design (we stayed on the 3rd floor). The rooms were clean but small, and there was not enough space to open two suitcases at the same time.
The only negative part was the showers that made the whole bathroom wet. They probably had a cheap contractor for that!
The staff were very polite, the internet speed was good, and it was quiet in a peaceful neighborhood.
The location was very convenient. It was right beside the metro station, with access to the red and blue lines. We got to Kadikoy in less than 15 minutes with it. You also can get to Sabiha airport by metro, but it took us an hour to get to Istanbul airport.
You can walk 10 minutes to Migros grocery store, 5 minutes to a dry cleaner, or 15 minutes to the City shopping center.
