We liked absolutely everything about this apartment (ok, small comment at the end :) ). Photos on the web-site fully correspond to what we found in the apartment. Well-equipped, had everything - including a hairdryer, an iron, even a device for racklet! Microwave, fridge, dishwasher. Clean, comfortable. Warm enough. Has enough space for 4 skies in the entrance hall of the apartment itself, so no issues.
Very comfortable and enough of space for 4 adult people. Can be used for 5 if needed (one bed can be 'stretched' side-wise), but will be a bit crowded, I believe.
Nice balcony (could be nice to sit in summer with a view on Mont Blanc, but we were in winter, skiing al the day).
Ski-in/ski-out! Many shops on the ground floor of the building. Bars/restaurant - the same building (no noise at all, as the windows go to the opposite side, and it's on a high floor), Nice view on Mont Blanc - every day!
The apartment is near Charvet bus stop of Arcs 1800 (50 meters), from where one can easily go to Arcs 1600 to get funicular down to Bourg Saint Morits. 5 minutes walk to the second village of Arcs 1800 (Villards), but they are actually smoothly connected to each other, so not an issue at all.
Internet: 15 euro for the whole week (from the Arcs-wide internet provided) - a pure bargain, nothing to compalin! Decent (but not particularly fast) connection, was fully enough for us.
One small issue: no English channels at all on TV. But, it seems, it is a genearal issue for many private-owned apartments. (though, we speak some French, so it was not actually an issue for us at all).
Overall - highly recommended!
Special thanks to the owners - Pierre. Though we haven't met Pierre in person and communicated only by e-mail, but everything was nicely organized from his side, we easily found the keys upon arrival. All (and honest) information was provided in advance, thanks!
Will definitely use it again if we go back to Arcs! (will do, of course :) )
