This apartment was perfect for our purpose, and could have easily accommodated two more adults or children (we were a couple on a work-cation). The apartment is well situated within easy walking distance of a weekly market in summer, grocery store year round, and several nice restaurants and bars. The tourism office in town offers next to nothing in services - just a map of trails local to Les Houches, or some souvenirs to buy (still worth dropping in for local event info). A bus station is equally as close, and for summer hiking you are about 15-20 minutes from the closest lift (Bellevue), and 30 from Prarion (MTB/VTT). The drive to Chamonix is simple, and should take you less than 10 minutes on average.
The apartment itself offers views from the master bedroom, spare room and kitchen that all grant uninterrupted views of the mountains. The apartment is easy to air our and get a cross breeze going on warm days.
The kitchen is adequate for most cooking you would plan to do on a vacation. There is no tea kettle that we saw, so we used the coffee pot to heat up water. There is a stove, microwave, oven, medium-small refrigerator, and a small freezer. The bathroom has a small shower, but plenty of space for two people to get around each other. The washing machine is located in the bathroom, and is adequate for one load a day due to the slow speed of eco-machines. Clothes need to be hung dried, and a wrack is provided for that too.
If you rent through VRBO, some of the information from Carlo's other personal page doesn't transfer. He doesn't provide towels (we weren't aware of this), and he needs you to inform him if you need sheets for the beds (very European to expect people to travel with sheets and towels). A side note, he doesn't speak French (Italian or enough English to convey what needs to be conveyed).
A parking space is provided for one vehicle in front of the apartment. You have to climb two sets of stared (one to the ground level from the parking area, and one to the second floor [first floor if your a European]).
Last points: We did not have contact with Carlo prior to arrival, and thus followed the instructions from VRBO - to meet the owner at 1600. We arrived promptly at 1600 to find that he was packing out to leave as he had been messaging us all day. I suggest you contact him immediately to arrange the rendez-vous. We nearly missed him.
