We really enjoyed our stay at Giannis's apartment. The property was very clean, nicely decorated and had everything we needed. The real highlight is the roof terrace which is huge, with a hot tub (ideally only for 2 people at a time) and stunning views of the Acropolis. We could have spent the whole of our trip enjoying the sunshine here!!
Location wise the apartment was located in a great place near to many bars, restaurants and the main sites. But worth bearing in mind that this also means that there is noise from the bars in the street below which carries to the bedroom and while we were there went on till the early hours.
Most of our communication was with Harry who was extremely prompt with his responses and also checked in throughout our stay to make sure things were ok. On our final day we were able to leave our luggage at the nearby cafe also run by Giannis and he was extremely helpful in getting us a taxi on to our next destination, particularly when we were leaving on a public holiday when public transport was cancelled and all taxis were booked up.
We'd 100% recommend Athens, Giannnis and Harry as hosts and the apartment we stayed in.
