Juliette told us to be there before 3pm as she has other engagements so we rushed to the place (by taking an expensive Uber) from the train terminal but end up waiting by the street for more than an hour under hot sun. During that one hour we couldn't reach Juliette on the phone at all (no pick-up) so it was quite worrying and we weren't sure what to do, we had our luggage with us so we couldn't go anywhere either. When Juliette finally got back to us she mentioned she had some trouble and asked us to wait for a further few hours with several more delays. She originally suggested that we wait a few hours then take an Uber to collect the keys from another location from someone else but we suggested that we will wait nearby. At that point Juliette wasn't too helpful as she also complained about our arrival time - despite what was agreed beforehand. The few hours waiting was very stressful as Juliette wasn't responsive and it was my first time in Paris, everything was quite foreign to me. We also missed our tour which we originally planned for that afternoon and sat in a nearby restaurant waiting for hours. The restaurant owner didn't seem happy with us too as our luggage were in the way in the tiny restaurant space. Juliette did apologise at the end and agreed to reimburse our salad (from the restaurant) as compensation for the long wait but I haven't received any news/reimbursement on this until now.
About the apartment - be prepared to climb five levels of narrow and winding stairs to the top floor (no elevators and dimly-lit). I couldn't get my luggage up on my own (without risking injury) and grateful that I'm traveling with a friend so we took turn to help each other out - took us at least 20 mins+ and lots of hard work to get our luggage up (and down). Host wasn't there to help, Juliette's sister turned up to pass us the keys (after the long wait) and left immediately after.
Upon arriving in the house, the bed wasn't made and we had a sight of the yellowish mattress and pillows. We had to make our own bed and Juliette wanted guests to remove the pillow covers, bed sheet and quilt cover before leaving - so make sure to budget some time for this in your travel schedule.
Apart from everything the apartment is stylish (with Parisian features, small balcony and nice lighting) and it is in a trendy area of Paris - Voltaire, near to the Metro Station.
