Building has no elevator so you have to carry your luggage to the last level... There was no water pressure in the morning so basically there was no water during the days but only during the nights. The problem is a municipality problem not Isik's problem. Other than that it was a pleasant stay and Isik is a really helpful host and a super responsive one. Location is really close to Taksim square and it is accessible by Uber or Careem. If you're arriving by Havabus from the airport it is in the parallel street to the dropoff location.
