We stayed in the apartment with 4 adolescent men. The apartment and balcony are nice and spacial, comparable to the pictures. Matrasses were not very comfortable but still okay. Not all suggested sleeping spots were equally comfortable, so the apartment would best fit 4-5 persons. Be aware that the neighbourhood is bad (chance of spotting heroin junkies during daytime and prostitution), so it's discommended to bring children. However, it's still only a 10-15 minutes walk to the city center and metro stations (with trains to acropolis, the harbour and airport), making it a good place to start your adventures. Because of the low price, I can recommend the apartment, as long as you consider the pros and cons.
