We had a wonderful time at Era House. The host and co-host were extremely helpful and hospitable. The apartment has an amazing view and it's equipped with everything to make your stay worthwhile. It's also in a central location so places like Taksim and Galata aren't very far.
The apartment itself is very clean and well maintained. There's a rooftop which gives an uninterrupted view of the sea. We would definitely stay again at Era house if we're ever in the area.
