Just returned from a stay at this place - it was absolutely lovely. The family who run the place are very warm & welcoming. Our room was very spacious, clean, tidy and the beds really comfortable. There's plenty of space to dry your ski gear in your room if you need to and the bathroom is large (by Austrian standards) and the shower always had a good supply of hot water. The breakfast room was nicely laid out - we were offered cooked ham & eggs every morning which was great & set us up for the day.
The pension is situated a little out of the village of Soll and after a hard day's skiing can be a little tiring on the legs walking back - there are ski buses every morning from the end of the road (opposite the Hotel Alpen Panorama) which we found to be reliable.
Top Tip: There is no internet/Wi fi at the Erhart but we went to the Alpen Panorama next door for a drink/meal and they have free wifi if you enter your guestcard number which you should have been provided with from wherever you are staying in Soll).
Overall this was a great place/excellent value for money and I wouldn't hesitate in visiting again.
