This apartment is way smaller than it looks and is very basic. It is a great location for walking Madrid. The internet was also good.
The big issue was the noise. There is a bar on the ground floor of the building and the noise from it ( and surrounding neighbourhood bars) made sleep a rare and precious commodity. Friday and Saturday nights in particular are terrible - bar and street noise until 3:00am - even earplugs couldn’t drown it out.
So not good for a restful stay. Cannot recommend.
