The staff were very helpful. They gave us milk for our son and access to clean our baby bottles. We accidentally put the no cleaning sign on our door but they gave us fresh towels and emptied bins on request. They stored our buggy downstairs too which was a great help and as space, like in most buildings in Paris it seems, is limited.
The beds, shower and toilet were all excellent for a 3 star hotel. We had breakfast at the hotel each morning too, which I can fully recommend.
