Assuming that bus 98 is a direct bus from the airport to the hotel along the coast (still displayed as 98 on Google) If you didn't find it at the airport and heard it, it was abolished in August 2019. We used a tram to the city. I walked with a heavy suitcase for about 10 minutes.
However, there is a regular bus departing from Terminal 1 and you can take a 12 or 32 bus without a transfer for 20 minutes. The cost of the bus is 1.5 euros, but if you stay a few days, the free pass for 15 days is 15 euros.
