This is the best Airbnb that we have ever stayed in. The apartment is located right next to the 35 piste in Campo Carlo Mango and a five minute ski in the morning gives you access to Predalago and Groste before the queues start to build. We actually preferred staying in CCM rather than MDC, having done the latter last year. It is a little more low key but has all the amenities you need; bars, restaurants, supermarket etc. and MDC is only a five minute drive or bus ride anyway.
In terms of the apartment itself, it has recently been refurbished to an impeccable standard and is a lovely place to be. The beds are very comfortable and the bed linen beautiful. The photos don't really do it justice - it is fantastic. We had a great week and all wished we could have stayed for longer, it was that good.
My only other advice would be to book skis and tuition with companies other than the ones in CCM. We may have been a bit unlucky but our instructor wasn't great, was late too and then cut our lesson short by ten minutes.
Also, having arrived on a Thursday, the ski hire shop didn't have much stuff in (even though we'd emailed in advance and they'd confirmed they had the skis my wife wanted) and we felt like we were given what they had rather than the ideal kit. We would recommend Olimpionico Sport or for ski hire and Scuola Italiana Sci Nazionale Des Alpes - we used them last year and they were good.
But please don't let this free advice detract from Sabina's apartment - it is really great and the communication, check in and advice were all brilliant. Highly recommended. :)
