The place is super cozy and clean, but the best feature is how accessible it is for my parent. The place is in the 1st floor (only 5 stairs!!) and super close to the metro station so we don't have to hike a lot.
Emre is also very kind as he helped us to order a taxi to the airport (the driver is someone he knows more than 10 years so we can trust him), we ended up paying very affordable price with the meter-taxi compared to the expensive private transfer.
After all, our Istanbul trip was great with staying in a good place with great host, it is a very recommended place to stay in!
