Anne's place was wonderful! Monmarte is the perfect place to stay if you want to stay in a lively area but not in the overwhelming center of the city (but still close to it).
Location wise - the place was perfect for us, only a 3 minute walk from Blanche metro station, on a quiet street but right near the action of Monmarte. A quick walk up to Sacre Coer and surrounded by everything we needed - pharmacy, restaurants, markets etc. We utilized the Metro daily and it can truly connect you to anything you want in Paris (being from Texas, we weren't used to using the Metro, however it was very clearly labeled and easy to use).
The flat itself was so cute! Enough space for 2 people to move around in for sure, the shower was GREAT and the kitchen is very large considering the location, with updated appliances throughout. We had everything we needed.
Anne was very responsive to all of our questions, responding within minutes. Check in/check out worked perfectly fine - Anne was waiting for us upon our arrival with a glass of wine :)
Overall, a very positive experience. Safe area, nice flat, good host and good location.
