Oh no! This must have been frightening. I hope your daughter is ok? What a horrible experience. As said before please report this.
When i walked through Portugal in 2016 I stayed at an Albergue and there was a local man hanging around. When i was showering that evening I turned round and he was staring through the window at me
It was so horrible. I think its something he had been doing a while. There was no Albergue host and I ended up going to a local cafe for help as the man kept coming to the front of the albergue and looking in. I found someone who spoke a bit of english and through google translate managed to communicate what happened. Someone went and found the man and told him to leave. Another pilgrim arrived who could speak English and they wrote a note about what happened and left it for the host who wasnt going to be there till the next morning after we left. I was terrified all night the man would come back and barely slept.
