We were keen on visiting many of Madrid's attractions near the city center, and for that, the location of Nuria's apartment cannot be beaten. It's right near Puerta del Sol, a huge metro stop, so you can get anywhere in the city easily. The apartment is cozy but had everything we needed. We made extensive use of the washer/dryer, a welcome inclusion, as was the elevator (we had several bags with us). Nuria met us when we arrived and walked us through everything, also giving us an opportunity to brush up on our Spanish (her English is good but it'll be easier if you know some Spanish too). Later, when we had some trouble with the apartment's locks, she did her very best to help us over the phone, even late at night. We found her to be highly accessible and this helped us feel more comfortable.
