My stay had cons and pros: I didn't meet Abdurrahim, but he was communicative and responsive, his brother Ahmet did the check-in and he was nice and helpful and accommodating. They don't live there themselves.
The place is 25min (1.7km) by foot from Taksim's airport bus station and from Taksim is mostly flat/downhill but to get back to the main street it has very steep uphill. Their brother Barat was living in the living room, which I wasn't aware of. Another guest living in the other room. The front door needs to be banged to close and it's hard to open, so leaving early or coming back specially when people are sleeping makes it inconvenient for others. The toilet was constantly leaking and making sounds. The kitchen had dirty dishes left for a couple of days (Barat said they were his friend's) . You need to have your own lock for the room door. WiFi was weak inside the room but ok outside.
Two days there was strong smoking smell in the house, and from what I understood Barat smokes. I wanted a taxi to get to Taksim as it was steep and I had a suitcase, so Ahmed helped to get a taxi for me for 80TKY (I was told taxis don't go short distances), but I cancelled and when I myself got the first one from the street, it cost only 30TKY. Someone also had eaten my breakfast sandwich in the fridge that I wanted to have on the way to the airport. The room itself was spacious and quiet. I've tried to leave an honest review for improvements and future guest expectations.
