Upon arrival we were warmly welcomed by one co-worker.
Although the rooms are in an old building, the location is great, very close to Monastiraki square and two other metro stations.
The room we stayed in was spacious and with basic equipment. This guesthouse is a very convenient place to spend a couple of nights in central Athens that we would recommend if you have a small budget. However, if you aren't willing to share very basic toilets/showers then it's not the place for you. :)
