Transporation from Budapest Airport

I will be traveling with three other adults to Budapest on August 18.

We are staying at the Hotel Moments, Andrássy út 8., Budapest, 1061 Hungary.

Approximately, how much will a taxi cost from the airport to my hotel?

Does the airport run taxi service have large size vehicles, like vans? Will a taxi be able to accommodate 4 adults and luggage (at least 1 large suitcase @ and probably one carry on size?

Thank you for your help
