don't know from where to start but i recommend definietly musa's place first it's clean not just clean very clean to the point you can smell the cleaning products they are so professional they check up on you every morning and ask if you need something , secondly musa and his collegues are kind and answer anyquestion they even can direct you to any place you need to go , thirdly it's a very safe and touristic place close to the Galat tower and just one street up to the istiklal also close to the metro station i really had fun and spend incredible days , hope to come back soon :) !
