I spent 4 nights at Eric's place in Montmartre. The neighborhood is on the hill and 10 mins walk to the Sacré-Cœur church. It's quiet and convenient with lots of local restaurants nearby.
The place and the hospitality are impeccable. Eric is a thoughtful host and accommodate our needs (e.g. temp luggage storage after check out, a list of recommendation of restaurant nearby). For whom is considering this place, go for it and you won't regret!
