The appartment is well located next to a metro and in a living quarter. It is very functional.
The bed was a little bit too hard for us.
There is an partial elevator : you need to take the stairs for 1/2 floor. (not very convenient with a stroller) but we took the habit with the subway in Madrid which have no elevator either.
We really liked the deco even if the doors are not so quiet when you slide it to open (in the night with kids).
Finally we enjoy our stay but maybe not come back because of the stairs and bed.
