Meso was a great host that communicated quickly and clearly. We arrived at around 00:30 but had no problems with check in.
The apartment was in a perfect location close to the old town and also right next to a tram stop so we could explore other areas easily.
Meso also arranged transportation from the airport to the apartment. There was an issue coming from the airport as the vehicle had no baby seat which we had requested. This was the only small negative on our experience but I can highly recommend Meso as a host and this apartment to explore Istanbul.
