Good: An excellent location for the first timers, lovers of night life and city slickers that want a bit of taste in their temporary dwelling. Plaza Catalunya 1 min walk, cafes food and shopping next door (Paseo Gràcia). Air conditioning, clean bathrooms, stylish interior. Can continue with dieting if needed as has a comprehensive supermarket next door in el Corte Ingles and the full kitchen in the apartment. A few gyms within walking distance.
Bad: the other side of the convenience - this is the ‘tourist central’ which attracts thieves, street vendors. Huge unending crowds of tourists. Prepare for drunken brawls in the street in the morning and occasionally the police presence (nightlife is close by). However it’s still a civilised place like anywhere in the developed world so no need for alarm.
Also easy to put on a few pounds of fat around your sides and face from inordinate eating of fast carbs, if you don’t watch it. Better seafood stuff - go away from the city centre and find some local places to eat.
Some Michelin stars restaurants we have visited - nothing special. Don’t expect too much. The local places in and in the vicinity of Barcelona can be way better. Do some home work if you want quality food (and experience).
