Oltian is a great host, the instructions to enter the apartment were very clear, and we always had communication with him. He responds very quickly to messages. He took care of our baggage at the first and last day of our trip, so we could continue getting to know the city. It was a very nice gesture.
I had read many reviews about the neighborhood and was not sure of what to expect. However, it was not bad. One of the streets that leads to the place is kinda dirty, but the other one goes right through a park is it is nicer.
Also,the apt is very close (5-15 min walking) to Psiri, Monasteriki and the Acropolis, which was very convenient because we barely needed to use the metro or buses.
I noticied that there were other tourists staying at the building, and I think that the rooms there might be a popular place to rent for a stay.
Last but not least, you have an amazing view of the acropolis from the terrace! Definitely chrck it out.
