Good for the price, cheap hostel in a nice area (close to Belleville), we spent one night here on a weekend in Paris.
We loved staying at San Remo Hostel, the staff are lovely and helpful and there is a kitchen so you can cook your own food. There is a computer with free internet and it has a lovely atmosphere!!
We loved staying at The Scream House, it's a clean hostel with it's own kitchen, the owners are friendly and there was always someone there to let us in, the location is good, about 15 minutes walk from the train station and well connected to metro lines. It is also located in a really cool old apartment block. My only complaint is not enough bathrooms! Otherwise a really good vibe at the scream house
