I stayed in the City Chalet for three nights. On arrival, we were met at the chalet by one of the MTL team, and he gave us a comprehensive tour of the apartment with useful hints and tips on the apartment and local area.
We thought the kitchen and bathroom facilities were excellent, and the whole apartment was very clean. The beds were comfortable with some of the best sheets I have ever slept in !
We used the two bedrooms towards the rear of the property, and they were well away from the main road traffic noise.
I would definitely stay in the City Chalet again.
Something that didn't bother us, but could be useful to note for other potential visitors - there are some very steep steps to the front door of the property.
