The check-in process was excellent. Gemma sent us a beneficial information book about the crucial things of the accommodation and the neighborhood. The flat was spotless, and there was some beer in the fridge! As the house rule said, there was one set of European adapters in the apartment, but we could use only one of them. If you have more electronic devices, it should be helpful to bring some adapters with you. We had enough towels and pillows (in the wardrobe there was also a Wellpur pillow, which was super comfy). The kitchen is very modern and has all equipment you need. Only one thing was a little bit uncomfortable for us: we booked the apartment so that two adults could sleep in a separate, lockable room so that no one needed to be in the living room. Unfortunately, the small room turned out to be cramped and dim: if we closed the door, there was no air, and if we opened the window, the sound of the air conditioner outside was disturbing. Air conditioning was only in the living room, and although there are fans in the rooms, they were loud, so we could not use them in the evenings.
So in the end, one of us slept on the sofa in the living room and turned on the AC, and the other slept with the door open in the bigger room.
