The apartment is really quite spacious, airy, comfortable, spotlessly clean and very well situated, especially if you want to enjoy the night life of Heraklion. Since air planes fly over the old town, silence isn't exactly perfect, but life isn't perfect. Marena and her neighbor Poppy were always available for any assistance and, as most Cretans, were warm and welcoming.
I had a great stay here, but my friend who's highly allergic did seem to feel a bit the presence of potential cat hair (?). Nothing which didn't make her enjoy the stay as well, but worthy of noting.
Over all, a highly recommended place for fun days and nights in Heraklion.
