[Olga]

Добрый день.
Проверьте, пожалуйста, упражнение. Тема "transport and travel". Нужно написать иностранцу письмо, какими способами можно добраться до своего города из Москвы. Спасибо.

There are three ways to getting my city from Moscow’s airport. The fastest way is a traveling by plane. On the other hand it’s the most expensive way. Also it is convenient a booking of a transfer from the airport to N.Novgorod. It is good that they will pick you up at airport but it’s less comfortable during traveling. It takes you 5 hours, maybe more because of the traffic jams. And the third way is a traveling by train. It takes you 8 hours on a usual train and 4 hours on the express train «Sapsan», which leaves from the Kazansky railway station. In this case you must get to the railway station by the local train «Aeroexpress». And some problems can appear because you don’t speak Russian.

Проверьте, пожалуйста, степени сравнения прилагательных. Спасибо.
