Yep. It'd be in shadow all the time which means it would be perpetually cold. 26 to 35 Kelvin cold.
Not so. From Wikipedia :
Surface temp.
min mean max
Equator 100 K 220 K 390 K
85ÂN [6] 70 K 130 K 230 K
(Near-surface) cave systems internally attain the mean temperature of their surface environment over a period of decades or centuries (depending considerably on the rate of heat movement by air flow ; negligible in this case). So a mean temperature of 220K is comparable to the Antarctic Plateau stations in winter, but doesn't have the wind chill. The 85deg N station shouldn't be much of a problem.
Our experience (an important word and concept that) with space stations of various types, from the Apollo 13 use of their lunar lander as a lifeboat to the present ISS and Tiangong 1 space stations (and the planned Tiangong 2 and successors) shows that temperature control is not insurmountable, at which point, the radiation and meteorite shielding becomes more of an issue.
