Stayed here for 5 days, it was a last minute trip as my plans had changed, I've been to Istanbul twice before so I'm a little familiar with the area, especially taksim.
The location is absolutely perfect, 10/10
Shops, bars, cafes, restaurants on your doorstep, literally 1 minute from taksim Square.
House is small but was perfect for both of us.
Constant hot water, great aircon, comfortable bed, plenty of towels, blankets, sheets etc
Toilet paper and drinking water provided.
Kitchen equipment
Washing machine
Satellite TV... Only a few English speaking news channels
All in all it was perfect for our short stay
I would recommend this place for location and amenities
Communication with host was great
No problems at all.
