Nice apartment 30 minutes form the centre of Madrid. Very convenient layout for 4 people (2 bedrooms) and comfy sofa for two more (really comfy). Comfy beds - really good sleep. You have everything to live here for your stay. Important mention for summer - there are cealing air mixers instead of a/c, but they seem solid and effective.
There is a metro station abiut 5-7 minutes away and a direct bus from the centre including Atocha station. There are plenty of shops and local cafe's around, including well assorted Aldi nearby.
This is Madrid, so it is recommended to travel without a car. Do not plan to park on the street - it seems hardly to find. Hovewer - at the beginning of the street there is a garage advertising ~10 EUR a day, but I did not checked details and avaliablity. It is really better to travel by public transport.
During our stay Jose was on permanent stanby, asking I he could help and everything was OK - thanks for that :)
