We recently spent time at the Royal Regency. Several high points. The staff is very helpful. Nicholas was wonderful in getting us reservations to a wonderful restaurant nearby, Restaurant L'Estaminet. Thank you!
We arrived about an hour before our room was ready, and we were upgraded to a 2 bedroom unit that was available. We ended up using the second bedroom as a dressing room. The unit has everything you might need. I think we may have been in an unrefurbished apartment. The carpet was a bit dingy and the bathroom needed some cosmetic repair, but so what? We didn't come to Paris to stay in an apartment.
The 15 minute walk to the subway wasn't bad, unless you were worn out from walking around Paris all day!
The hotel was a good place to stay when visiting Paris. Hint: Remember to bring those good walking shoes with you!
