We really enjoyed our 1 month stay in the Carlo’s apartment! It has everything inside for a quiet and comfortable life. The apartment is located far from the center, but close to Sabiha airport: if you arrive or depart from this airport, you can get there very quickly. The metro and Marmaray can be reached by buses, the bus stop is close enough, we use the buses every weekend and sometimes on weekdays. Also within walking distance there is a huge number of supermarkets, shops and bakeries, in the middle of the month people working there already began to recognize us :)
The only possible improvement: the speed of the Internet. If you need to make a lot of video calls for work or for living, then the speed may not be enough (for calls without video and for YouTube the speed is enough).
Carlo, thank you again for our wonderful stay, wish you all the best!
