We just left Karola's place yesterday and really loved it! Karola was a very gracious host and made sure we were all set up before she left. We loved the place itself, it was cozy and charming. Plus it was a bonus to look out our window and see the Sacre-Coeur in the distance. We walked up to it on our first day. The neighbourhood is very vibrant and has good grocery stores and bakeries and other shops nearby. It's located very close to the Metro and bus stops too. Right now there is a transit strike in Paris, which makes getting around a total headache, but we got to where we needed using the bus stops nearby plus line 4 in the Metro during it's abbreviated opening hours (6:30-9:30 AM, 4:30-7:30 PM). Highly recommend.
