The hotel is located in a central area with tram, ferry and bus stations only a few minutes away. Also many cafés and the Galata tower are nearby.
The hotel itself is quite large with many rooms that seem to differ a lot in size (although from the same category). Our first room was quite small and the last renovation of the room seemed to have been done without passion. Also, there was quite a lot of corrosion in the bathroom. We had problems with the toilet flush and the water in the wash basin not running. The hotel immediately reacted, they repaired the problems, but we got a new room anyways. The second room was noticeable bigger and also in a better condition, although there was again some corrosion in the bathroom. Both rooms were clean.
The personnel was very friendly.
We also had breakfast (7€ extra per day) which was good. Nothing super fancy, but what you can expect in my opinion from a 3-star hotel.
So, overall, I would recommend the hotel if you look for a relatively cheap hotel in a very central location and plan to mainly stay in the hotel for sleeping and breakfast
