Gitte,
Not sure when you are going to Barcelona - and this may be after the fact, but we were there in late October and stayed right down on the Ramblas at the Hotel Continental. We had read NOT to stay there, that it was noisy etc etc. But we did and we loved it and would go back in a heart-beat.
Now, this is not a luxury hotel - but then we are not luxury travelers, and by the time we book our cruises, we have to watch for good deals for air and hotels. That's just the way it is with retired educators on a budget! At least we get to go and we're not complaining.
We paid 95 Euros and booked the deluxe balcony room. I think they have 4. We arrived around 11 AM and since their breakfast buffet was open until noon, we took plates and went to eat on our balcony (weather was still good). They have everything on the buffet from boiled eggs, prunes, raisins, fresh fruit,juices, cereals, cheeses, yogurts, toast, jam, all kinds of pastry. And they leave tea,coffee, milk, and some other things available 24 hours.
We loved having the balcony and watching the action from there. We could see jugglers, mimes, and hear the music. We LOVED Barcelona.
The room had 2 large beds together, one was very hard, the other was med hard. Nice linens and pillows. There was a tiny frigo bar and a microwave. There was a ceiling fan, and very nice and clean bathroom. I took a picture of the room if you would like to see it. I had bought ear-plugs but we didn't need them, and just fell asleep to the haunting street music.
On the morning we left for the airport, we had the front desk call us a taxi. The clerk told us to wait and have coffee until he called us. He had a monitor of the street and when the taxi arrived, we took the lift down and had no problem at all. The charge for the taxi - including luggage and tip was about 20 euros.
Probably more than you ever wanted to know, but just in case you aren't up for the $$$, I thought you might like to hear about a budget hotel!
Have a great trip.
