I stayed here for 4 nights with my husband and 1 year old daughter over the Christmas holidays. The location is great, with a bus stop that takes you to Plaza España right outside the door. It’s also surrounded with markets and small shops for your grocery needs. The place itself is decent. Its a semi-basement apartment with one big window facing an apartment building. It’s great if you’re jet lagged and want to get some extra sleep but not to stay in during the day. As it’s facing apartment buildings, it’s not as private if you want to open the window shade to let some natural light in or air out the place. Lack of natural lighting aside, the apartment has everything you need for a short stay, including a washing machine. Jesus is very accommodating and answered all our enquiries before and during our stay. I would definitely stay here again next time I’m in Madrid for a short time as it’s well connected to the central area.
