I had a really great time at Marta's place. The apartment is as you can see in the pictures very nicely furnished with many details and a wonderfully large terrace. Exarchia with a lot of cafes and interesting places is about 15min walk away, for the center you can take the bus. Marta is a very friendly and uncomplicated person and I felt very comfortable in the apartment. If you’re interested, ask her if you can drop by her ceramic studio, it’s beautiful!
