We had a lovely time at Alaaddin's apartment in Beyoglu. The apartment was great and suited all our needs. It is also really well placed to explore the city as there are many great restaurants, shops and bars nearby. I would probably avoid it if you are not keen on loud music, however, as there is quite a lot of noise late into the night..but if you are eager to experience the the hustle and bustle and energy of Istanbul then this place is for you.
Alaaddin and his wife were both very welcoming and friendly and we had some lovely breakfasts downstairs in his cafe. I would definitely stay there again...our holiday was a great success. THANK YOU! x
