I know this is an older post but I just wanted to make some corrections and give additional pointers. The telephone at the hut is only operational from the end of june to the begining of Sept while the hut is open. The number in the origional post is correct. Our mobile phone is +39 338 94 78 838. We are in Italy from mid-april to mid-october. Outside these times we can be contacted by e-mail;

Concerning the climbing of the Jorasses in august: early august is best. The weather in late august can take a turn towards winter but there are always fewer people then. We did suffer glacial damage below the reposoir in 2003 but not as badly as in other places around the Mt. Blanc. It requires a bit of zigzaging to get through the lower reaches of the planpincieux glacier which can add bit of time to any time given in guidebooks. Most books rate the climb an AD but it is leaning more towards the D side of things especially in august. Weekends in august should be avoided if you are interested in a tranquil climb. As with most huts in the alps, always call if you want to sleep the night and/or eat a meal. In order of proficiency; we speak Italian, English, French, Spanish, Portugese.
