The flat at Place d'Italie is perfectly suited to one person to stay. Yes, it is tiny, which shouldn't be a surprise as it is advertised as tiny.
As others have said, it is well placed to metro stations, restaurants and shopping. Coffee, tea and bits and pieces are all there. It's a very handy spot and I would recommend staying there.
Delphine and Adil were helpful, welcoming, friendly and supportive to this weary traveller. I'm ver grateful to them.
