Appartment was fine but there was no heating so the room was really cold. I had to sit in my coat under the wraps. Then I had to sleep in a scarf. If I had a hat, I would sleep in it. In my opinion you shouldn't rent an apartment in winter if you don't have good isolation or heating. Electric heater would be sufficient but according to the host heating is not a basic service, in my opinion it is especially when windows can't be closed properly. I don't go on holidays to sit in a room with a coat on therefore I find no heating unacceptable. It's not my first time in Spain and heating was provided everywhere. Hopefully I won't get sick after this night.
