Before you book this apartment, remember to ask Carlo about the hidden late check-in charge which isn't mentioned in his listing. We checked in at 4pm, 2 hours later than the stated 2pm check-in, and Carlo charged a whopping 50 euros for our 'late' check-in. He claimed it was for his cleaner Rada who had to wait for us, but she wasn't even aware of the charge.
Carlo wasn't around when we arrived. He instructed Rada to bring us to the apartment, who does not speak a single word of English. This was rather inconvenient as we had a load of laundry to wash. When we asked her how to use the washer (instructions in French), she simply shrugged and motioned that she did not know.
The apartment's dimly lit, not very clean, and we found mop strands in the kitchen sink. It was noisy every night as there's a stretch of pubs just across the apartment. Overall, not a very pleasant or memorable stay. For the amount you're paying, you can do much better elsewhere in Paris.
