Dorotea's apartment is highly recommended!
We loved it!
We arrived after midnight, Dorothea and her husband waited for us, and welcomed us to the apartment. Also they prepared some basic groceries for the us, for the first morning breakfast. Thanks!!
The apartment has the perfect location in the center, walking 2 minutes to Syntagma square, 5 minutes to Monastiraki.
It was perfectly clean, and had all you need for comfortable stay.
The kitchen is not big, comfortable for 3 and for preparing light meals, but might be small for 4 or if you want to cook. Other rooms are very nice and large. The balcony is great for letting air in, and relax, but since it's in the center, you also hear lot's of music and the crowd noises until quite late at night.
