Whats sort of accommodation do you prefer?

When I'm on holiday at the sea I prefer to stay at a hotel. The major advantages are, cleaning the room by the staff and meals that are included but sometimes it can be expensive. When we travel with a big group of people it's better to rent an apartment. Usually the apartment is bigger than the hotel suite and can include two-three rooms. Also, there is a fully equipped kitchen that is convenient. So, it depends on the kind of holidays that you are going to have and the number of guests.

****You do not need also and too in the same sentence.
