Well furnished apartment with high ceilings, a nice balcony and a lots of charm. We stayed with out 18 month old and it worked perfectly: Guendalina provided a cot and the place was very kid friendly.
Once we got the hang of transport (trams seemed much more reliable than buses, metro good too though a longer walk to station), it was easy to zip in and out of the centre.
The immediate area was quite residential (e.g. not touristy) with some nice restaurants, a supermarket and bakery very close by.
