The only thing I missed is that there weren't any spare bedsheets for the sofa-bed. However, the advertisement stated that technically there were 2 beds, including the sofa. But we could not use it since there weren't any bedsheets to put on it and it wasn't clean enough to sleep directly on it.
All else was OK, the apartment is very cool and well-located. Tim was very comunicative and it was easy to access the flat.
