We stayed at Nick's for two nights in July. He was super helpful throughout our entire stay, suggesting places to visit, showing us around the neighbourhood (which ended up being our favourite spot in Athens!) as soon as we arrived on our first day. The room and bathroom are newly refurbished, modern and clean, and I really don't think we could have been any luckier with our stay in Athens!
We went to a few cafes and restaurants close by the flat which were all amazing (definitely try a restaurant called Black Sheep, our favourite restaurant in Athens which Nick recommended)- furthermore, the area is only a short distance walk from the presidential residency, the main square, and other main spots.
