Ali is a very good host. We only contacted the days prior to check-in and checkout and during the processes. Ali met me on the street outside the house to show me the entrance to the building and the apartment. He gave me 30 minutes extra on the checkout day with no questions asked. He is a very pleasant and humble person. I recommend him as a host.
His apartment is as described, suits all of your needs. It is ok for two people to live in.
It is situated on a hill, so you'd have to walk up and down a little, but everything you might need is not more than 15 minutes away by foot (the restaurants and shops of Nisantasi, Macka park, Osmanbey metro station). The grocery stores are just around the corner.
I recommend this apartment!
