This apartment is set in the courtyard of a larger apartment block, and uses the space it has well. Very open plan so if two of you are using both beds there is not a huge amount of privacy. Belleville has enough around it to entertain you, but the apartment is very well connected via public transport and near to two amazing parks in Paris.
There was some noise early in the morning whilst we were there, but that may not be a permanent feature. Also, this is good in the summer, but the apartment in itself kept cool.
We were two friends travelling together, and I would say the apartment is better for a couple than for people using both beds, but the description is accurate and it was a lovely place to stay.
