We arrived earlier than expected but Omer sent one of his friends who tirelessly spent around 3 hours with us around the neighborhood and on the terrace and introduced us to a lot of things and places that made our experience easier! The neighborhood is calm and well located, a walk away from the ferry, the tram, the bus stops, the Galata bridge and tower. Even though we rarely contacted Omer as his friend Shah helped us a lot on the first day, he was always there when we reached for him to enquire about something tricky. He contacted us a couple of times to ensure our short stay at his place was going well.
The place might be small for groups but we only needed it for sleeping and resting as we were traveling for sight seeing and a couple of football matches! So being small was not a big problem, it was cosy and just as described, clean and with all amenities listed working.
Unless you're looking for a really spacious place, I would def. recommend for future visitors.
