Gina's house is at the forth floor of old building located within a minute walk from the metro station, and easy access to the central part of Buenos Aires. It is facing a busy street and a bit noisy as some others reported. The building is old but with an elevator, and the rooms are remodeled and clean. The bathtub was a bit small for me to take a shower, and the supply of hot water was a bit limited. Breakfast is simple and basic: coffee/tea, milk, bread, cereal. Gina is always very quick to respond. There was a little difficulty in direct communication because Gina does not speak English and I do not speak Spanish, but we could communicate well through mail with the help of google translation.
Overall, it is a good buy for those with a limited budget.
