You really want to have a real taste of the modern/cool/trendy/artistry Istanbul then you MUST stay in MODA. Hazar's place is in the very heart of Moda, a place full of pubs, bars, restaurants and other cool places.
The apartment looks better in reality, it's spacious enough for a family of 4 and a big cat. The wifi works, the A/C does a great job, the hot water is instant and the beds are really comfortable.
Hazar sent via online shopping some water and sweets as a welcome (Thank you!) and made himself available during the day for any questions we had.
