Vahan is a communicative host and very accommodating, he went out of his way even to reach us after check out since we forgot a charger, and offered flexibility with luggage storing.
The place is in a good location if you will use the train, for the centre you might need to take a metro. I didn't find it too scary at night as a woman near the station, but also I am always very aware of my surroundings.
The place itself is big, kitchen could be improved. The fridge can be used but it was very smelly. Bathroom was okay, clean and big. The room was comfy, big and well equipped.
In summary, good for a short stay, and Vahan is a very kind host :)
