Me and my fiancé were traveling with my parents and younger sister. The home is obviously beautiful and was welcome to come home to each day. It was a wonderful size for us and was perfect walking/uber distance from everything we enjoyed, including the garden district, business district, french quarter and even further east. We rented a car but if all in your group are happy to walk and you’re exploring the high points of the city, I don’t think this is necessary.
The 1 shower situation was no problem for us. Worth a note, the age of the house does not insulate sounds too well across one floor, so heavy snoring may be heard by all :) Though, when my parents were awake early in the mornings we did not hear them at all between the up and downstairs.
D-M herself was wonderful - easy to communicate with, cheery and excited to share recommendations, and very helpful.
This beautiful home was the icing on our wonderful, delicious trip.
