Silvias quirky home is a few minutes walk to the Metro so everything is so easy to get to. I walked from Silvias place to the Champs Elysee at a leisurely pace, crossing the Seine passing the Louvre, Eiffel Tower in around 40 minutes, it was a terrific walk and of course there were plenty of coffee shops on the way. The room, as mentioned in the other reviews is very low with beams, at over 6ft tall it's not ideal of course but to be honest it wasn't a real problem.
Silvia was a delight and a very relaxed host. If you need a base to explore Paris I would certainly recommend.
