Gemma's house was great for a few days. It is in a local area with many restaurants, shops and a metro nearby. The apartment does not have much light, although worked for my group of 4 guests just fine for a few days. The mattresses are not the best although it is not an uncomfortable sleep. The apartment is quiet and has a small balcony for 2 people to stand on.
At the apartment there were no maps and very little toilet paper, so be prepared to bring your own. Other than that the stay was good - thanks again!
