This is a perfect location to stay in! Very close to Galata Tower and just up the street from the metro station, bus stop, and taxi stands. Very central location to reach the various sights you will be touring in Istanbul. Our host was quick to reply to our needs and had good communication.
Despite being in a busy area it wasn’t too loud for us, though if you are a light sleeper you should bring ear plugs, as we were awakened by late night revelers going down the street outside. But noise is expected in such an urban setting and anywhere you stay in Istanbul you are likely to experience noisemakers.
