Teresa's apartment is within viewing distance of the Eiffel tower, amazing view! Very central to lots of restaurants, markets. Walking distance to the RER and bus's.
Lots of restaurants in walking distance too; but beware late lunches ... most places close at about 2p-3p and reopen after 6pm.
There is a bike rental kiosk just on the next block that you can use to bike the canal down to the Louvre and beyond.
BEWARE though -Veilib is the bike rental co - download their app and go online to set up an account. Otherwise, if you do it at the kiosk; they charge your account $150/bike until they confirm it is returned, and THEN credit your account 5-10 days later. But great way to see the city. Some bike lanes; but sometimes just go with traffic. EVERYone has to practice defensive driving/biking/walking.
Teresa has a hot water pot or coffee by the cup maker; so just what you need to start the day. Bakery on the block with quiche, croissants, coffee.
