I spent about 1 month at Virginia's house while moving to Madrid indefenitely. She is honestly the best host one could find. She provides literally anything you may need in the apartment and is there for advice, help, support, in the complete respect of your personal space (remember to return the favour everyone!). The room where I stayed is next to a private bathroom and has its own kitchen corner, fridge, work desk, work chair (I repeat, she thought of everything). The house is 5min walk to metro n.4 (30min to Gran Via), at least 3 buses to the city center are just across the street. 3 supermarkets just around the corner (one closes at midnight). Less than 5min walk from restaurants and a pub. 20min walk to shopping center Arturo Soria Plaza (plenty of food and drinks). I needed other type of services as documents printing, christmas gadgets etc., I found everything walking 50m from the apartment. There is a post office in front of the house. I can also say I walked around the area safely by myself at night. I highly recommend staying at Virginia's.
