The appartment was really nice and clean. The communication with Ermanes was swift and he even offered to pick me up from the airport.The metro connection into the city center and to Gaia is really good so even though one could walk, I often used public transportation.
For the mezzanine one should maybe bring a small bag to bring up and down toiletries.
Overall, I had a really good time and can only recommend Eramanes' place.
