The apartment is an easy walk from Atocha train station (where airport train arrives) and located between Anton Martin and Lavapies metro station.
The apartment is very small but very clean.
I slept fine on the pullout bed. I was also alone so the space was ok for one person and a bag however I think it could be a struggle with a second person and bag.
The apartment is also on second floor with no elevator - something to consider if you have a heavy bag.
I was pleased with this accommodation though and would stay here again. Great value.
