What a convenient location! I prefer the Europe metro than Saint Lazare. Europe metro feels shorter of a distance but has 3 flights of stairs. Saint Lazare feels further and uphill for most of the way. It is also on the same line as Pere Lachaise cemetery where Jim Morrison, Oscar Wilde, Chopin and many of Napolone's generals.
The bed is super comfy. Definitely only one person! The building and area felt safe to me. Bring earplugs since some of the neighbors get home around 3am on a Sat night. The heater for the place was perfect. You can control it too.
Helga and Lena were very quick to respond to all my questions. They were super helpful and great at communicating.
If I'm traveling solo again, I'll book this place again for sure.
