We had a great time at Fabios's place!
IMO the location is the biggest advantage. It is a bit above Vigo di Fassa away from the milling tourist masses and screaming children around the town center, and it has truly awesome views in all directions. Enjoy your breakfast or dinner outside on Fabio's patio, while watching the sunrise or sunset on one of the magnificent mountain ranges that surround the village. The 'above the village' location also ensures that you do not need to spend a lot of time in the traffic congestion that plagues the valley for getting to some awesome hiking trails. Just pop out of his parking lot and drive up the mountain to the Karerpass or Paolina ski lift (in summer it doubles as a hiker lift), or down into the village to the Catinaccio tram line (bring a N95/FFP2 mask if you care about social distancing - they tend to pack the tram cars tightly).
The apartment is pretty nice and clean, and there are also great views from the windows. The space is pretty tight, but functional. The bathroom is well designed, even has a bidet and a washing machine. The kitchen is useful, but the cooking gear is basic and there is no oven, just a cook top. The place is very quiet since it is far away from the major thoroughfare in the valley, but there are some early birds living on the same street who will be dieseling to work right under your bedroom window at 5-6 am. We considered this a perfect 'alarm clock' since when it comes to hiking, the early bird gets the sunshine in the morning before the frequent afternoon thunderstorms (and a parking spot directly at the tram/lift station and not half a mile away...;-). If you rather want to sleep in bring some good ear plugs...
A note about the 'king size' bed that is advertised: I think is a bit 'lost in translation': I am 180cm (6'), and my feet were sticking out from the mattress. It is also rather narrow. I think for American standards it could be called a 'double twin'.
Aside from these minor complaints, I can only recommend renting this place. We liked being there a lot and we would definitely consider renting it again.
