Sylvies place is in an excellent area for exploring all areas of Paris. The apartment is small but neat, clean & very quiet. There are lots of lovely restaurants and bars just outside the front door and a yummi bakery at the end of the street. The apartment is on the 3rd floor accessed by a steep staircase and no lift (very common in Paris).
The closest metro is 3mins around the corner and 5mins to the metro to gare du nord.
I highly recommend this little gem.
