A very nicely appointed complex though 'chalet' is a bit of a misnomer, its really a large block with different sized apartments. Location is OK in that its 5 minutes from the centre, up a hill, and it isn't exactly ski-in, ski-out. Ski-in isn't easy for the non-expert and ski-out requires a walk of maybe a couple of hundred metros down an icy walk. This may seem picky, but everywhere else in VT is genuine ski-in/out.
The apartment has everything you'd need and the staff were really very helpful when we had problems (no hot water one evening, quickly sorted). Car parking at 70€ per week in the underground car park is necessary as there are no cars allowed park on-street in VT.
There is a (small) swimming pool and sauna, good enough to ease aching bones. There's free wi-fi but the number of connections isn't great so you may have to queue to get one. Once you're online then hold it and don't close the computer. Sitting on the free internet connection and blocking others my not seem like good citizenship but everybody else is doing it. Internet isn't fast by BTW, so no skipping home !
VT is at 2,300m in altitude so unless you're coming from a high altitude location it will take some days to become acclimatized. Sleep quality may not be great, and you may wake in the morning with a stuffy nose which quickly disappears, but that's what you get at altitude.
However, people come to VT for the skiing, and the skiing around VT is wonderful. Weekends are actually best as its the day for transfers as guests leave for home, or new guests arrive. If you're looking for a place which can accommodate a large group or extended family, then I'd recommend Chalet Altitude. I'm giving it a 4 rather than a 5 since it does look a little lived in and worn, but otherwise its pretty good.
