I stayed at Dominique place just one night, but I enjoy it totally 100%. The place is very cozy, with French atmosphere. The bed is comfortable, I was sleeping like a baby :)
Location is great! 10~15 min walking from Gare du Nord and 3 min walking from Gare de l'Est.
Dominique is nice and friendly person! For sure I will stay again at his place my next time in Paris!
