We have been coming to this hotel since 2005 and have enjoyed our stay tremendously each time. However, it may not be for everyone (read below). The location is perfect, the cafe scene is unmatched and most of all, the atmosphere is authentically Parisian (by virtue of its location in the 6eme arrondissement).
Our room was spartan and small, but was big enough for my sister and me. It had 2 comfortable twin beds, a bathroom with a bathtub (and wall hairdryer) and a small refrigerator. There are 2 tables for working, if you so desire (the hotel has very good internet access). There is also a main kitchen on the ground floor that supplies plates, glasses, utensils and a wine opener. All in all, we found our room and the hotel perfect.
Hotel La Louisiane is centrally located, with good access to the metro. My sister and I walked 12-14 hours a day for the first 4 days. On our last 2 days, we combined taking the metro and walking. Using the hotel as our starting point everyday, we were able to cover the 1st to the 8th arrondissement. To us, this is what makes the hotel's location quite special.
Room service was good. Our room was cleaned and towels replenished daily.
Every member of the team we interacted with was professional and friendly. We felt very welcomed! We are looking forward to our next trip and staying at the hotel again.
