Helga's place is very central, and comfortable for lonely travelers. I bought a 3-day subway pass when I arrived, and it was a waste.:) Helga was very communicative, and responded to my messages about Paris in general very promptly. Though I should warn claustrophobics who doesn't know how tiny most Parisien apts are that this is an extremely tiny room/studette, and might not be for all for more than 1-2 nights. Otherwise, great host, and good value for the location!
