The place is really well located in Paris, close to at least 2 metro lines and in a nice not-so-busy area of the city, with boulangeries, restaurants, and a lovely Sunday market. It's a good place for a couple nights for max 2 people.
During my stay the TV decoder wasn't working properly so we missed the chance to watch some French news after walking all day. Mind you the place does not have a hairdryer, so keep it into account if you have long hair and decide to stay here during the winter months. Everything was accurate and Gerson is a great host!
