As previous reviews have mentioned the situation is in many ways perfect. Very near metro station, surrounded by many boutique shops, restaurants, street food outlets, fascinating Jewish bakeries. In easy walking distance of several museums, art galleries etc. The Seine is in easy walking distance.
Apartment is small but we had two lots of couples staying & things worked out ok. Both beds were very comfortable. Agency were quite responsive for extra bath towels, bed linen etc. They even changed the washing machine as it wasn’t working properly.
We spent a very enjoyable month there. Would recommend it.
