Yes. It is very small (by American standards). I think there may be a few steps to reach it, but not a flight of stairs. Depending on which floor you are on, you may have to take one elevator and switch over to another (some may be directly accessible from the ground, ours was not). It's fine with luggage. I would reach out to them to see if you have a wheelchair or other restrictions.

The cost of a taxi from the main train station to Pendini was about 8 euros or $9. It was about the same returning to the train station from Pendini.

The suite I stayed in had two bedrooms - one would sleep two and the other would sleep 3 (two singles pushed together to form one bed plus a separate single). There was only one bathroom. However, check with the hotel to see if there might be configurations with more than one bathroom.

Stayed there in March 2023 with a room overlooking the piazza. Music continues to blare from the restaurant every night past midnight. Ni.ce view but it was really hard sleeping. Recommend getting a room at the back

I don't remember the exact amount but it was less than 30 EU for a taxi from airport to hotel.
