Great little apartment, perfect if you're a couple.
Nice location with all the amenities you'd need, but a bit outside the centre - a 20 minute walk will get you into la rambla.
Not really walking distance of the beach (would take about 45-50mins), but is very close to the Fontana metro station (5 min walk) so we just got the metro to Barceloneta, from which the beach is a 10 minute walk.
Only downside of the apartment is that it doesn't get much natural light (even the balcony) which is a shame when you're in a lovely hot country with lots of sun! Had to have the lights on all hours of the day, but not really that big a deal if you're out and about most of the day like we were.
