Lizabeth and Yacqueline were both super helpful from the first day I arrived. As an international student, I was very overwhelmed but they gave me all the tips I could need as a foreigner in Spain. For example, they spent 45 minutes with me trying to book me an appointment to get my metro card, something that would have stressed me out otherwise!
Although their English is limited, they speak very clearly and were very good to explain things differently if I did not understand. The place was also always kept very clean which I appreciated. Despite the apartment being a little ways away from the center (sol), there were groceries stores, restaurants, a library, metro station etc. within a 5-7 minute walking distance. Also, the neighborhood is very quiet and extremely safe so if you plan on going out at night, you don't have to worry about walking alone at night.
The one thing I would recommend to anyone travelling to Spain in the winter though is to bring warm clothing! To save money, heat is rarely used (anywhere) so the nights can get pretty cold! My hosts ended up buying me an insert for the duvet on my bed when they noticed that I was cold which I really appreciated.
