Julia's flat is very close to the main tourist places with the metro just a couple blocks down the street, there's also many restaurants well with in walking distance.
The bed was super comfortable, but the room is right next to the stair well so theres some noise that comes in during the night (if you're a light sleeper, keep that in mind)
otherwise, Julia is a great host that replies very quickly (i locked my self out and she was at the door in no time) and is there to help! definitely recommend.
