I spent a week in March in Montseti and had a wonderful time! The apartment is spacious, clean and fully furnished in alpine style with all the facilities in the building (ski room, garage, etc).
The building is right in front of the slopes, 2 minutes away from the local bars and shops and half a minute from the chairlift which is a dream! You're up skiing in no time and at the end of the day you won't have to worry about a lengthy journey back. I look forward to come back next year!
