I have been stayed at this apartment for 10 days and it was fantastic for many reasons :
1st the host Erol was very helpful, fluent in english, gentel and easy to comunicate with him.
2nd you will get the befinets of the radisson hotel which is very clean building, parking place and very clean gym indoor pool and sauna, the staff are very kind.
3rd the location was good easy to acsess the metro and the bus station under the hotel can take you direct to the center.
4th many restuarnts near the hotels ( same building) migros and bim on the opposite side.
5th and it was very important for me that the clients of the radisson are very kind not anything.
6th the apartment have inglass balcony nice furniture and all u need in the kitchen.
7th the nice view on the 14 floor.
I recomend this property, i came from sweden and when i will visit istanbul next time, this will be my place.
