Rue de Bourgogne runs parallet to Des Invalides (one street back) down to La Seine. It is one-way going away from the river. This is the main entry-way. Most buildings of this era in Paris have an inner court-yard, some with lovely gardens. I have shown you my court-yard earlier on Face-Book.
I am renting a small studio on the 4th floor. The ground floor in Paris is 0. There is the tiniest of lifts, but it works a treat thus far, with nary a creak.
As there is just me in the apartment, I leave the sofa made up as a bed all the time. The outlook from the window is a delight, with lots of fresh air which I need. The only thing missing is something to play music. I do have a zillion tv channels, but SKY (UK) is abyssmal. I quite like Aljazeera (from DOHA) and find it very even-handed staffed by proper journalists from around the world. How I have solved the music problem is to listen to Classic-FM via the ABC online.
That is me up there on the 4th floor (0, 1, 2, 3, 4)- right there under the eaves with the window open.
