I recommend it.
Communication with the owner/lessor was fast (by the way, there is free WiFi on Taksim if needed - remember that if you have heavy suitcases and you only need to communicate via wifi - do it from Taksim). The suitcases can be left for a short time also in the next tea room. The apartment is well equipped, spacious, the price corresponds to the service provided. The equipment, dishes, ... are at the other hand not new, but they are fully functional and fully compliant. However, the washing machine at my arrival would deserve cleaning (previous user probably interrupted the washing cycle and ...); I believe that the owner cleaned already the washing machine. The street is quiet, shops and all services within easy reach. The subway and funicular are a short walk away - but the street is on a steep slope (remember it if you have heavy baggages).
Do not trust in the garden / terrace too much - it's nice plus of the appartment, but it is just a small yard in the courtyard.
Anyway - the accommodation suited me very well and I will be happy to return there on my next visit, if it is free. I definitely recommend it to you.
