St. Anton am Arlberg, Austria

Though it's a cozy ski resort, there's no way you would get me to live in St. Anton am Arlberg (population about 2,000). Why? It's located in a very, very narrow valley with steep mountains rising abruptly on all sides. It's the middle of May and this town is deserted. I drop by the tourist office and learn the place shuts down in May. Every hotel is closed. The main street (it's just about the only street) is closed to motor vehicles---which is nice. I don't think the jet-setters come here in the winter judging by the absence of a single clothes boutique, jeweler or watch shop.I count two grocery stores, a sporting goods shop, several banks, a bakery and that pretty much sums up the shopping possibilities. A toll road through the mountains passes through the narrow valley.

Is this place hopping or is it dead in the summer?
Don't come in May that's for sure.

Is there a lake and/or golf course in town?

Arriving by car the only option?
Trains stop here.

Does the place feel claustrophobic?

Lots of choices for acccomodations (hotels/ chalets) and do I have recommendations?
Doesn't look like it to me.

Could I spend a whole summer here or would I get bored?
Three days would be the max.
