Great apartment, very close to the local sights and a 5 minute walk to the metro. There are a few shops along the street handy for essentials and a great organic shop at the top of the street. Check out a restaurant called Lamucca a few streets along, good food and quaint setting on a hill. Metro back to the airport very straight forward and only 4.90 Euros. Also, the open air lido is only half hour travel on the metro-good pool and grounds but take a packed lunch as there was no café on site when we visited in June. Get there early as long queues too.
Enjoy your stay!
