This is a very spacious apartment in a great, central neighborhood. The two bedroom/two bath combination is great. We comfortably slept 3 adults and one baby. Would be great for 4 adults.
The space is quite dark, lit only by lamps. Even the person who checked us in had a hard time finding the lighting because none of the main area/bedroom light switches are actually functional for guests. Thankfully it has lots of windows so some light was let in during the dreary Paris days.
The biggest downside is that it was VERY cold. We were told that the heat was managed by the building but it never turned on... something I've never experienced in Paris. There is one space heater but it doesn't warm a room. We were constantly moving bedding to the living room to stay warm while lounging.
