The overall experience of my family in 8 nights at Erol's house has been totally positive and we had a very nice stay there. The pros and cons of the house in summery are as follows, hope it helps other guests:
Pros:
1- location is great, loads of cafes, bars, restaurants just downstairs, a few meters walking to Istiklal street, and 5 min walking to metro station.
2- the house was immaculately clean, higher than our expectation, spacious, we had a family of 8 without any issues.
3- Erol left some stuff for us which surprised us, ex: breakfast stuff, cleaning stuff, etc.
4- The house was well decorated, everything seems newly refurbished,
5- Erol respons to email has been quick, really helpful and polite. He accepted to keep our stuff in the house for couple of hours after check out before another guest arrived, which was really helpful for us, Thanks Erol.
Cons:
1- The house is on the 4th floor in an old apartment without lift
2- The night club and cafe noise may bother you at night especially over the weekend, Erol left some earplugs in that case. He was honest and had informed us about that issue in the ad.
