First, let me say the apartment is in a great location close to public transportation stations and tons of restaurants and shopping. It was really wonderful to just walk outside and already be part of the action. We often just watched people from our windows. Paulina was also very accommodating when we had an extra guest for 2 nights.
This apartment was great insight into how Parisian apartments are like, however, be aware it's reeeal tight! Even with just 3 people for 1 week, we used every possible table and floor space for our stuff. The double bed is a sofa bed/futon (and it's in the kitchen/living room area) and the twin bed is in a child's bedroom which felt awkward to sleep in as an adult. The bathroom is small and does not fit more than 1 person which is especially hard if you have multiples getting ready to go out. We just had to get creative and use the kitchen sink and other mirrors in the home. The bathroom also smelled mildew-y so we had to prop the window open whenever it was in use, but we appreciated the heater in there.
Bring or expect to bring toiletries. We had only 1 toilet paper roll provided so we had to do a 10pm run to the store to get more (Thankfully they were open!).
It gets loud in the streets especially Thurs nights thru Sat nights so it was hard to sleep sometimes. Outlets are sparse and we couldn't figure out the heater in the bedroom. The apartment was a great value and we overall enjoyed our stay, but there were definitely some adjustments we did not expect.
