really nice place
Great plus: location & Diego (the manager)
Minus: thin walls
So yes, if you happen to have noisy neighbour (which the hotel policy forbids of course), you might get bothered, but otherwise the place is pretty neat.
It's right by "las ramblas", plaza catalunya & Grand Via, so a great location.
Finally the big plus is Diego, the mananger, who makes you feel at home and is very helpfull & availalble if you need any help or have questions about the place or anything in Barclona.
Just one advice; if you did not get a chance to specify an estimated arrival time at the place, or if the plan changed, give a call to let know when you will arrive (even 30 mn before, when at the airport), so you make sure Diego will be there (he somethimes needs to go to other locations but he is mostly at this one).
2 ways to get there from the airport: the train is the fastest and cheapest (3 euros - exit at Passeig de Gracia) but the aerobus will bring you a little closer to the place, at plaza catalunya (5 euros).
