This was a perfect place for me to stay in Nice.
First, it is accessed via mews, in the interior of the block, so it does not border a street or sidewalk, meaning there is zero traffic noise. That's a real blessing for me.
Second, housekeeping is by request only, so the environmental and labour costs of housekeeping are minimized. The bed was perfectly firm for me, and linens/pillows very comfortable. Shower and bathroom generally were spacious and worked well.
Third, the location is great - very near an SNCF station and about a five minute walk from the nearest metro tram station at Jean Medecin.
Fourth, they reached out to me a day or two ahead of time and provided good directions to the hotel.
I really liked this place - I will certainly consider staying here again on my next visit to Nice.
