Good points:
- this is a clean, functional apartment
- convenient location, close to Barcelona Sants & a couple of metro stops; within walking distance of certain attractions; an excellent collection of nearby supermarkets
- responsive customer service team who were always on hand and replied to messages very fast; they dealt with issues (missing kettle, broken cabinet door) very quickly
- a bath tub (a rare treat these days)
Not so good points:
- I found it extremely over-priced (but then, this was my first stay in Barcelona)
- the dining chairs are damaged, have broken backs, and should be replaced before someone gets hurt
- although the balcony and terrace look good in the photos, in reality they are overlooked by many windows and completely lack any sense of privacy
- the street is sporadically noisy at night, with various noisy trucks emptying trash, cleaning the street, etc, and sometimes people walking past and talking loudly
- the electrical outlets seem weirdly and inconveniently placed, i.e. none next to the bed or the sofa, but across the room
- don't expect the apartment to look as fresh as in the photos; it is becoming worn and tired looking, with some items seen in the photos having disappeared (e.g. the chair cushions on the terrace)
