Good location close to many sightseeing destinations. Quiet neighborhood. Very friendly staff always ready to help. The breakfast was nice, altough we were surprised to see them make orange juice from concentrate and tap water. We didn't get any tummyaches however, so that was okay. The hotel was clean and altogether well-maintained, well earned 3 stars.
You can book transportation to and from the airport from the hotel, but there are much cheaper alternatives advertised close to the hotel. So we booked a minibus transport to the hotel beforehand, but bought the return trip at half price from an agency near the hotel.
The room was okay, quite small and for some reason a spare bed we didn't need blocking the open floor. Heating didn't work which made the nights quite a chilly experience as we visited Istanbul in January. Also, hot water always ran out around 9 am as probably the entire hotel was taking a shower around that time.
