Galini Pension is a less than 10 minute walk to the port of Ios. Bernice offered very detailed directions for walking once we arrived (since I had completely forgotten they offered transport to and from the port). She was very helpful in arranging transport to the port for the next day.
Our ferry was scheduled to arrive sooner than check in but Bernice informed us that if our room wasn't ready, we could leave our bags. Our room was ready when we arrived and Bernice gave us a bunch of tips about how to get around the island and some places to eat and visit.
As for our room, it was as described - my sister and I did notice that the shower curtain didn't really contain the water in the shower so make sure you bring some flip flops you don't mind getting wet to bring into the bathroom. They do provide bar soap, but make sure to have your own shampoo and conditioner.
The room had AC, which was very welcoming considering how hot it was. There was also a mini fridge with some water.
This residence suited our needs for our stay and was very close to the port. Thanks Bernice!
