This is a great option for your Istanbul stay especially if you use Istanbulkart.
The size is quite comfortable compared to all the hotels in istanbul. All the hotels there have really tiny rooms. I stayed at taksim and galata area as well so i have an idea. The only thing is that this place is not bursting with tourists(which might be a good thing for some people) otherwise it is right next to a bus stop and public transport in istanbul is really good and well connected.
This was my first Airbnb experience and it was great! The placed felt secure and the view is not bad too.
The best part is clearly the host. She
Is an amazing person. She helped us with planning our days in istanbul, translating for us, recommended some amazing restaurants and such a nice person.
