Nice little set of servicesld apartments in a refurbished old building in a vibrant area of Istanbul. The specific area is on a side street away from the main streets outside but very close to the Galata Tower and the shopping areas leading up to Taksim Square.
The room is clean and comfortable. Be warned that there is no lift and you may be required to go up some cramped steps to get to your room. Check in advance if this might be an issue for you.
The shower and toilet are clean and new. Good power and temperature for the shower water. A small desk and extra seating provides some extra room. There is also a kettle and a fridge.
Windows are thin so light sleepers should be wary.
Having a 24/7 reception is very useful as well and you get a small leaflet recommending nearby places to eat and drink.
