We, a family of six, had a great time at Vivian's place. Very spacious, the apartment had everything we needed. Vivian answered within minutes! The location is very central, only 3 metro stops away from the center of Athens. We bought the 5 days pass and used the public transport. The neighbourhood is safe, lots of restaurants, cafes, bars around, it's close to the university and lots of young people are around. 2 days we went by tram to the beach (30 min) which was very relaxing... The weather was perfect for sightseeing (around 25°) and it was not crowded at that time of the year.
We would always come back, thanks a lot for your hospitality, Vivian!
