We spent 4 nights at Vaggelis’s place and had a very good time. The host is friendly and proactive in making your journey work.
The location is directly up the road of many many restaurants and coffee stores. A vegan/vegetarian coffee shop directly outside of the door, which makes great americano.
We walked around 15k steps per day, including a visit of the most interesting sights which are directly down the road.
The location is in an area of the city which is also very hardly hit by the economical situation, many places are closed or abandoned. At no point of the trip did we feel unsafe, but some of the empty dark roads might appear a bit scary at night - so bring a good friend for your exploration trips through this amazing city.
