The bathroom has no door, so you either stay alone or are very, very familiar to your partner. The room is big, very good located and noiseless because faces an almost pedestrian street.
We never met Edu but Charlie and he's NOT a person who manage things gracefully... I saw a couple of guests standing outside, in the rain, just because they got there 20 minutes before time and he wouldn't even let them wait in the hall. We had an issue too: Friday night we came back home from the club and the key wasn't working at the upstairs door (there are 3: front door, landing door and room door). After trying hard for half an hour we decided to call him and he was very reluctant to show up and help, even if he lives downstairs. It was very early in the morning, and I totally get that he was sleeping and it's a pain in the ass but hey, it's his business and the door was locked in a way we couldn't open it. Finally he showed up and realized the latch was halfway, stuck, so the key couldn't open it. He shouted to the people in our neighbor rooms to wake up and open, because he said that it was their fault for not closing properly. In a nutshell, if you're down for it and you don't care about the no door bathroom, cross your fingers to find the door properly closed!
