We'd stay here again. The location was absolutely perfect; we could walk to almost everything we wanted to see on the Right Bank, and did. Huge bathroom; comfortable bed; serviceable kitchen for cooking a few meals at home. However, the building did get a bit noisy at night, as there seem to be quite a few students living in the building.
We did have a few hiccups related to our arrangements to rent the apartment and check in. After originally renting the apartment for a period of five days, we submitted an alteration request for a sixth day which Katty said she did not receive. Upon follow-up, she said it would be possible to stay an additional day but we would have to pay 130€ cash upon check-in. We were uncomfortable with this arrangement and asked whether we could handle the payment through AirBNB. Katty then referred us to her boss and said she was leaving on a two-week vacation so we opted not to pursue it and to leave Paris a day early.
Finally, we had a miscommunication about our check-in time. The apartment was still being cleaned when we arrived and the previous occupant's luggage was still in it, although we'd clearly stated the time we planned to arrive and no one had ever said prior to that. that the apartment wouldn't be available for check-in then. However, Roman, the property manager, was very kind and accommodating. He took our luggage and told us to come back in a couple hours, and when we returned from lunch at a brasserie down the street there was a bottle of champagne and two glasses waiting on the table.
Our stay was nonetheless wonderful and mostly uneventful after that. Best meal we had in the neighborhood all week was fondue at Pain, Vin, Fromage, and the bakery on the corner of Gravilliers and Temple is amazing.
