This apartment is in a fantastic location. For transport there is a metro line right outside the front door that runs across Paris. Bus #63 is also across the road and runs to the Gare de Lyon in one direction and all along Rue de Germain in the opposite direction to within 10 min walk of Eiffel Tower. We also used Lime Scooters a few times and there were always plenty near the apartment.
For food you are surrounded by restaurants from every nationality; French, Thai, Vietnamese, Italian, Mexican, Indian. Plus across the road is a boulangerie, chacuterie, boucherie and poison shops.
Within a 10 min walk there is a food market, The Pantheon, The Grande Mosque (definitely worth a visit).
The English bookshop is also only 5 mins away.
If you can cope with the 5 floors of stairs, we did easily, then you won't find a better place. The beds are comfy, the kitchen well stocked and comfortable seating with picture postcard windows to look out of. We spent hours simply watching people out of them.
