The place is very clean and very safe. The apartment is spacious, and there is a bed for two but the couch can easily fit one more person. The location is perfect- it’s right behind Taksim square and has shops/taxis/metro a few meters away. The only setback is that there are a lot stairs so that took us a day or two to adjust to. But Mert helped us carry our bags and made the stay pleasent by constantly being in touch. He made sure we were safe and we were not lost in the city. So for that, I would say: go for it!! You definitely will not regret it :)
