The owners of the apartment, Jermain & Zübeyde, are a lovely couple. They are nice and super helpful. When we arrived, there was a football match at Besiktas stadium (close to the appartment) resulting in a road closure, so ourtaxi had to set us down almost a kilometre away from the apartment! Jermain was kind enough to help us with carrying all our luggage not only to the apartment but also all the way to the third floor (no lift). This would have been very difficult without his help.
The apartment is also cosy, with a balcony and a great view. The location of the apartment is also excellent, close to attractions and all sorts of public transport. There are also a couple of supermarkets less than a minute away from the apartment that sell all the essential stuff and are open from 7am until 2am!
There are however a few maintenance issues with the apartment. Most of the kitchen appliances are at the end of their life and need to be replaced. There is also only one air conditioning in the apartment, which struggles to cool the whole place down in hot days. The bedrooms can especially get hot, although there are fans that help (Jermain said that they are not allowed to put another air-conditioning for the bedrooms). There is also no exhaust fan in the bathroom!
We raised these with the owner before we left, and he was very receptive, so a few of these may have been already addressed by the time you are reading this :-)
