I loved my stay at this cozy little flat. I was a solo traveller and I gave to say the size is perfect for one person, it could work for two also or theoretically more if someone was to sleep on the couch but be mindful that there is zero storage space for more than one person, not even a place to hide away the luggages, so for maximum comfort, one or two works best.
Therr was everything I needed in the house and it was easy to feel like home and not in an empty hotel room. It was also surprisingly quiet for the central location that it had.
I loved the location it was a great stopping point to start exploring. Be vary though and this goes for most places in Istanbul, the area is better for young people, if you have difficulties with stairs or steep hills in general the city itself will be a struggle. I loved that though.
All in all a great experience and would for sure be back there.
