The apartment is in fact very good. It is on the hill side and with good lake view. The kitchen is really good. You can enjoy good view when you are cooking.
However, our first night was not so good. We spent quite some time to find the apartment. There are three apartments with no. 52: 52b, 52c, and 52. The owner should give hints about it. As the 52b and c are in front and besides 52, we have to try the key lock one by one. When it was dark and you were already exhausted, it definitely was not a good experience.
The apartment used electric storage boiler. The storage of hot water is limited and takes time to heat it up. The problem is we had no idea about it. We have two couples. Just one of the ladies washed her long hairs, the third person faced no hot water right during her showering. It was a terrible experience when the outside temperature was below 15C and you had to wash with freezing water.
It was not the end of the story. After my friend finished her bath with freezing water and wanted to come out for a hot coffee, she found that the bathroom lock was damage. She was locked inside. It took half an hour till the host sent his friend to show up. But he could not give any help as he brought no tool. The luck is we have brought a Swiss knives set with us. My friend used the tool to break down the lock and opened the door herself finally. She had already been locked for nearly one hour.
