Great spot for SHORT TERM stays (couple few nights) but NOT long term. Here's why:
The PROS:
Eduardo is very quick at replying, at all hours, and efficient at handling anything that crops up - couldn't ask for a better host in that regard.
The water is hot and long lasting.
It's a spacious apartment
Great/fast internet.
It's very close to the Tirso de Molina stop and associated grocery/restaurants/markets.
The CONS:
Super squeaky floors; there is no sneaking around or being quiet while others are sleeping.
The master shower drain is so slow, you'll be taking a bath while you shower.
The kitchen is NOT 'fully equipped' - basic cooking necessities are missing (can opener, oven mitt, large frying pan, cooking spoons, measuring spoons/cups, etc etc).
There is a washer, but no dryer, drying rack, or lines with clothespins.
The door is ridiculously difficult to unlock.
The front room is very loud practically 24/7 (it's on a main street near a main intersection).
It's an 'up and coming' area: we experienced noisy, dirty streets (condoms, tampons, dog and human feces) and noticed a constant police presence. Even so, we never felt unsafe... this is just FYI for those who are a bit particular about neighborhood ambiance.
