Julia was very very kind although we didn't met with her. She was worried about our arrival and guided us by phone. She left us the house rules and some tips about where to eat or drink a coffee.
Her room was fine for us, has a lot of space and is very bright. A little bit disorganized, but in general lines good to rest.
The apartment is perfectly located (very close to the metro station and a shopping avenue where you can find supermarkets, banks, restaurants, etc). The only thing is that the apartment is shared with 4 more people (seems to be students), so when you are planning to rent you should to take into account everything that implies.
