I cannot recommend this property because of the poor communication with Welkeys. I chose this property because of the professional conciergerie behind it as I thought that will ensure efficient problem solving if I would encounter any difficulties during my professional stay in Paris.
Reality was quite the contrary. I arrived to a cold apartment (to be expected in France in the winter) but with inadequante bedlinen. The duvet could hardly be called a duvet, it was so thin. I also only received two bath towels (I was the only guest) and no hand towels nor a towel for the bathroom floor. Ok, these things happen, but the worst part was communication with Welkeys. It took them several days to procure me with a proper duvet, I had to sleep with my coat on for three full nights. And the first solution was offered by an agent of the company who brought me her own duvets from her home! It took incredibly long for Welkeys to sort things out and procure me with a new duvet. And again, it was this same kind agent who went to buy the new duvet, although it is not part of her job in anyway. She also put a lot of pressure on Welkeys personally to get things sorted out in my appartment.
I didn't receive the missing towels before the fourth day of my stay either, but blockages in the bathroom sink and bathtub were fixed in a reasonable time.
The bathroom had no heating at all and this seem to be difficult to fix. On the last day of my 16-day stay I was informed that there is a remote control for a heater in the bathroom...
Communication was also very slow in general. The online Duve Guest Area provided by Welkeys has an online chat and displays a number that the guests can call if need arises. Neither one of these communication channels were in real time: it took typically 2 to 5 or even 13 hours for anyone to respond to a chat message or return a call! I also experienced a power cut (I had the washing machine and the dishwasher on at the same time, my own fault) and reached out to Welkeys for help in also that. They replied to me after 2 hours, when I had already gone through the appartment and fiddled around with all possible switches and found a solution fortunately without being electrocuted...
The Duve Guest Area is a joke also in other respects. All the information given there about the code for the front door and the wifi were wrong. Fortunately the aforementioned kind agent took the effort to double check with me these informations.
Check-out at 10 am is also something I have never encountered before. I wanted to rent through a company also to have flexibility, but no.
My stay was not a complete disaster, though. The appartment itself is practical. I fell ill of covid-19 and had to self-isolate for 8 days, and I was really happy to have such a functional kitchen. It is very well equipped for preparing different dishes and the fridge is big as well as the freezer. Food deliveries from supermarkets and restaurants work excellently in the area. The TV is smart and provides access for example to Netflix and France tv where you can watch the French tv channels through the Internet. The bed was very comfortable (I did not try the sofa bed). The bathroom was very lovely and recently renovated, so it seemed, and there was always hot water (which was really nice as there was no heating). The washing machine was wonderful, it has an dryer integrated, which was very important as it was difficult to dry anything in the chilly and damp appartement otherwise. The appartment is at walking distance from many interesting neighbourhoods and turistic attractions. Gare de Lyon is very close, too.
It should be mentioned that the appartment has no view, the windows all face a tiny inner courtyard with bikes and a shed for trash. It was very quiet, though, and if you mostly only sleep at the appartment it's OK. I was in self-isolation so a view would have been nice.
