I'll start from the good:
The location was great, right on the Spanish stairs, 1 minute walk from the Metro. Lots of shops, restaurants, and beautiful stareets to walk on. and very easy to navigate to the apartment+check-in/out.
On the other hand, the standards of the apartment itself isn't quite good, there's a lot of dust, no place to put the clothes (there's a clothes room but it's full with stuff like dust cleaner and ext).
More over, the bathroom is in a very bad shape, the a small leak from the shower and everytime someone takes a shower some parts of the floor will get wet until the next day(which is the next shower).
In our own opinion there were some things that we thought were missing in a standard Air BnB, like salt, oil, and ext.
We think the location is great and with some basic maintenance the apartment can get much better, and give a very good Air BnB experience.
