Marina is a great host, always available and she also gave us a lot of helpful recommendations concerning our stay. The location is perfect, Lavapies neighborhood is definitely worth visiting, colourfull and just 10-15m on foot to most Madrid attractions. The apartment is clean and comfy, however it is best recommended if you are planning to spend most of the day outdoors, since there is not much of natural lighting. This was our case, we spent most of our time sightseeing, so it didn't bother us at all. Over all, this was a great stay.
