We stayed just for one night at Mert's place, but we liked it a lot! The location is perfect for tourists since it's in 2 minutes walk from Taksim square, but the surroundings are quiet at night. The place is tidy, cozy and spacious, with many appliances that might be needed for a longer stay. The communication with Mert was smooth, he provided all the needed information and made the check-in/-out process flexible.
