We had a great time at Andreas & Hortense's place! The location is amazing, perfect for evening walks past the Seine whilst admiring the Tour Eiffel. The bathroom is great with a big bath, just be aware that the toilet is in there too and there's only a glass door, so make sure privacy between you and your fellow traveller is not an issue. The lights were a bit bright for our liking, but with the right settings and some candles, the place can be made very cozy. The only thing that bothered us were some 'disco lights' on the balcony that we couldn't turn off.
All in all, it was a great little base for us to explore Paris in and we enjoyed our stay a lot!
