We have just returned from a 10 day stay at Lola's apartment. The 10th Ard. Is a lively section of the city.
It is a great apartment in a central location, a typical Parisian size and close to transport, bars and restaurants. Two Metro stations within easy walking distance.
We would have no problem staying here again next time we are in Paris.
However if you have mobility issues, be aware that the apartment is on the 4th floor with access via a spiral staircase.
