I would absolutely recommend a stay in the apartment of Dalila!
Dalila is a very kind, easy to reach host, which makes the booking and your stay very easy.
The apartment is bright, very clean and the kitchen is stocked very well (with even a dishwasher :)).
The apartment is located in a quiet street, but very close by to place Jourdan, Luxembourg and de Londres. Besides this the apartment is located that it is easy to stroll around in the Flagey, Chatelain and Matonge area.
