Hello and welcome to
Symi ChatI'm guessing from your question that you've read about "all the steps on Symi" and are worried that you HAVE to climb flights of steps to get to Anastasia apartments. Well, you don't!
Chorio (The Village) is a settlement in its own right and whilst it is on a hill, there are few steps between your accommodation and the village centre with its bars, restaurants and shops. What you may be thinking of is the "Kali Strata" which is the route connecting Chorio and the harbour (Yialos). That is a wide avenue which climbs the hillside and consists of sloping sections and, yes, steps. A total of over 300. But you don't have to use that route if you don't want to. There is an hourly bus service from the harbour to the village (and beyond) and there are also taxis.
The bus will drop you at the top of the road where you will have a short downhill stroll to your accommodation. The taxi can take you to the bottom of that slope where the path to Anastasia is short and almost flat. Getting from Anastasia to the main bus stop in Chorio is more or less flat and will take you five minutes or so.
There is a flight of stairs from your apartments down onto the road where the bus can drop you if you want and whilst that is a flight of real steps (unlike the Kali Strata for instance) it's relatively short at around 20-30 steps (never counted them so could be wrong) and you can avoid them completely by getting on and off the bus at different places.
