Great location, just of La Rambla and in two minutes walk of the reat Metro system - don't forget to buy a "book" of 10 tickets that you can use on the metro and on the buses. You can go to the same places as the tour buses and at a fraction of the cost.
The hotel faces onto Placa San Augusti and yes there are some down and outs that frequent the square - probably because the church provides free meals for them - but we did not find them threatening. The rooms are good with plenty of space and a comfy bed. The soundproofing is not great, but if you read these reviews, you come armed with some ear plugs!
Breakfast was more than adequate. Cereals, yoghurts, variety of bread, cold cuts and cheese and a hot dish too. I agree the juice is awful, but have found similar all over southern Europe. Fresh fruit would have been good and with a fantastic market almost next door it would not have been too difficult to provide.
Overall a good hotel at a good price in a good location
