We stayed at Adrian's for two nights. The location is perfect, close to the underground and bus station. I did feel like everyone could hear you in the room, so there probably isn't much privacy, but since we basically only slept there this wasn't a problem as well. I wouldn't recommend this for longer stays or stays where you want to relax in your room as well. The bedroom has only a (squeaky) bed, nothing more. We liked eating breakfast on the balcony (
unfortunately the sun isn't on it yet in the morning, but we had luck with the weather). Breakfast (bread, butter, eggs, cereal, coffee, tea) was included. The owners are friendly (you share the place with them and one more room), and we could even leave our bags in the room at the day of our checkout. We had a great time!
