Summary: We liked our 1 wk stay in the area and cleverly arranged apartment very much.
Hosts: very organized prior to our arrival, provided local info before trip, accommodating to our later than agreed arrival.
There is a guest book (binder) with all pertinent info and instructions how to use premises (just like in a hotel). Welcoming bottle of wine.

Details:
The area within 20 min walking diameter around apartment is very popular for restaurants, private gallerias and small fashion shops.

Odeon Metro station 3 min away

We jogged (5 min away) in Luxembourg garden everyday in the morning.

We walked to major attractions (15-30 min): Louvre, D'Orsay, Orangerie museums, Notre Dame, Eifel, Champs-Elysees and so on.

Several groceries stores around apt.

Speaking of apartment: it is on 2nd floor. No elevator.
Compact, very practical. Clean. Newer appliances. Heater provided sufficient warmth for winter time (for us it was 15C outside weather throughout.) For us 3,
the water heater was sufficient for hot water.
