The host was very receptive and helpful, which was handy as there was an issue with the heating. The apartment was stone cold on entry (on a day when it was below zero outside) and the boiler wouldn’t work. We were given an electric heater for the first night but it was insufficient for the whole apartment.
To make things worse the boiler was leaking and there was a puddle of water around an electric extension outlet. We left it well alone!
Thankfully, the next day the host arranged for us to move to another apartment on the floor below, which was lovely and warm when we arrived and was perfect for the rest of our stay.
