I have only good impressions of this trip.
I had a modern equipped apartment had a single room with private bathroom at our request.
There is a buffet, also you could go to the shop and buy groceries. There are really good staff and teachers in Trinity College. They were qualified, responsive and friendly. They asked us to call them by their name. All weekend trips were included, so we didn't need to spend extra money.
On the first week, classes were held in the mornings, on the next week – in the afternoons (very comfortable for morning and non-morning persons). Every weekday you wake up, have breakfast, and with your group ride on the tram to the Trinity College in the Dublin's city center (it takes about 10 minutes).
Elisaveta liked her trip and we would gladly go there again in the next year.
Student was grouped the way, so there rarely were 2 Russian students in one group. The composition of groups as changing every week: someone just arrived, someone left. So that was interesting.
