Sorry wasn't sure if you meant the rooms or Lindos Gardens location. There are quite a few rooms close to reception, pool, etc which are pretty much on the level, the newer rooms are built on a hill behind these, so some higher than others. We were in the highest block (up by the infinity pool) and apart from the first drag with cases, it wasn't a problem.
To one side there was a good slope with a lift so far up, on the other side quite a few steps. We found the steps easier but I guess families with buggies, etc would have used the other route.
