My girlfriend and I spent two nights in Irene and would recommend it.
The hotel is a manageable walk from the port, approx 15mins, and easily navigable using Google maps. The local area has loads of great bars and shops, including a pretty square that is very popular in the evenings.
Our room was clean and comfortable, with the added benefit of having a shared rooftop balcony, and we had no idea the hotel had its own pool too.
All in all, a very comfortable stay and we were highly satisfied.
