Steph’s place is great. Small (one bedroom + a small living room), but more than enough for a couple that wants to spend most of the time wondering in the streets of Paris. Location was great, near restaurants and not too far from Notre Dame. Because of COVID we decided to not use the public transport (metro/bus) but it seemed to be well connected. We did rented Velib bikes, and there were plenty of stations near the Air BnB.
Would recommend staying at Steph’s!
