What a lovely apartment! I had a great week-long stay in Lia's place. Communication with her was quick and easy. Super comfy bed, great kitchen (including a washing machine, which came in very handy), fast wifi, really good heating, hot water, & water pressure. Great light from lots of windows. The elevator starts on the rez-de-chaussée (ground floor), unlike some Paris apartment buildings where it starts one floor up - very nice if you have heavy luggage!
Very close to the métro, pharmacy, grocery stores, fruit stands, bakeries (fantastic baguettes at the boulangerie/pâtisserie/chocolaterie across the street!), & restaurants.
There is also a biogroup lab about 10 minutes walk away that does pcr covid tests for travel WITHOUT an appointment - i got my results within 5 hrs.
