We arrived at Gare de Lyon station and managed to find our way to these apartments after only about 5 or so minutes. As we didn't have global roaming or internet we thought we'd find the apartment first, and then attempt to look for a phone box to call the owner (we found one right on the corner). The street (or lane) which houses these apartments is possibly one of the most beautiful and colourful streets in Paris and many photos were taken out the front.
Lucky for us, the beautiful neighbours across the road were sitting outside the front of their house enjoying the weekend, as it was a gorgeous day. They offered to call the owner for us which was terribly appreciated. The owner advised us of the access codes to get inside, so in we went. (We did advise the owner earlier of our exact arrival time so they were expecting us).
Our room was on the top floor. The stairs were a little steep and tricky to ascend, especially as I had just broken my arm and couldn't hod the banister properly. The room was cosy and featured an attractive wallpaper behind the bed, a small kitchenette, table, closet and bathroom. The apartment is small, however it is very affordable compared to other Parisian accommodation. Plus, it includes a kitchenette with mini-fridge and stove which means you can save money by cooking dinner (although, Paris restaurants are so good that we were reluctant to stay home at all).
The apartments are so close to everything you need: main train station, laundry, supermarkets, la Bastille, markets, hospitals, pharmacies, restaurants, cafés, bars... We walked all the way to the Eiffel Towel via the Seine from this hotel. Although a long day it is very possible.
We only met one owner who came to collect our money on the second day. She was very helpful with information regarding the nearby area.
We had an incident on a day-trip which meant we weren't able to return to this hotel for one night during our 4-night stay. We had left some of our valuables out for all to see (iPad) as we hadn't anticipated this incident. Upon our return, we found that our room had been cleaned while we were gone, and the iPad was still in its place which we were of course very pleased with as we were gone for 36 hours. The apartments have one main entry, where you need a code to enter, and then your room entry which requires a personal key.
Location, cost, amenities and security were the main positives of L'Hotel Particulier. My only suggestion would be to include some maps of Paris in the foyer, and to make checking-in easier for those guests who don't have access to a telephone. Also, free wi-fi would be greatly appreciated.
