Serder had terrific communication prior and during our stay. The location is great if you want to be in the galata neighborhood but keep in mind that the neighborhood itself is rather hilly and the apartment is a 5 floor walk-up. It always felt great to come home to the place after a long day exploring the city to pet the neighborhood cats, sip some tea and cool down in the air conditioned bedrooms. It was close enough to a lot of the tourist sights on the European side which made getting around fairly easy by foot if you can handle hills.
