Very affordable place with a location close to Taxsim Square which has loads of shopping and nightlife to keep you busy if you want to stay near. But Istanbul is a big city so explore it and you'll see some amazing stuff.
The stay is on a street with lot of grit and character and is a place you'll prefer if you're out for something authentic rather than something that screams tourist trap. The people there were all wonderful and helpful. There are small markets and eateries next to the stay that are very low price and have you covered for the basics.
The place is located on a steep hill with other steep hills surrounding it. This is not unique to Taxsim City Suites. Istanbul is full of steep and challenging hills to walk. So bring some good walking sneakers and say goodbye to any gyms. You'll get your workout walking the streets. :)
Suphi was a fantastic host (really, Suphi, thank you for the hospitality) that gave some great local tips and was always quick to respond with any concerns that I had. A great host and I had a great time. I would not hesitate to stay here again on another trip to this wonderful city.
