Safa is a magnificent host. He is there for you during check in.. Check out.. And you can reach him on phone in case something happened..
For the apartment.. It's cosy and comfortable with all amenities you may need.. Its location is very strategic.. 5 mins to Taksim square.. 10 mins to Havatas Bus Stop.. and 2 Supermarket infront of the building.. The area is very quit with no bars around so you will have good sleeping time.. House keeping is available if you needed and no one will go to your apartment without your permission..
I'd recommend Safa's place for any visitor and I'll be happy to go their again
