Myself and my boyf stayed in the Hotel Aneto for 3 nights from 5th-8th March 07...and we must say we found it excellent.
i chose the hotel as it was very cheap (€70per night for a double room), and its closeness to Placa Catalunya.

We arrived to the Hotel around 10.30 in the morning and even though check in wasnt until 2.00pm, they let us leave our luggage in our room and given time to get changed/ refreshed and told our room would be ready for us & to come back in an hour.

The room itself was basic enough, quite large but perfect for our needs. We only wanted it for a place to sleep really as we had so little time in Barca and wanted to see as much as we could.
The bed was quite comfortable, and the bathroom was v big. It had a bath with a shower hose, toilet and a huge mirror with counter for leaving things. there was also a large wardrobe in the bedroom with plenty of hangers and some shelves/drawers.
There was a tv but all the channels were Spanish. Our window however had no view only another window! There's also airconditing in our room.

While there was no breakfast included in our price there was a complimentary coffee machine(which we didn try) and free buns/pastries which is your typical brekkie. While its not to everyones taste its a handy kickstart to your day.

The location of the Hotel was great....While it is on the El Raval side of La Rambla it is (if even) 1 min walk to La Rambla and a 5 min Stroll to Placa Catalunya.

All the Staff were also v friendly (one in particular) and helped us with anything we needed to know.
The only downside perhaps is the noise level. You can hear people walking outside in the halls etc, and while it didn bother us and we were never disturbed by it, it may annoy some people.

I would recommend this Hotel if your on a budget but still want to be in the centre of things
