hello, if you budjget is about 100- 150 euro per night, dont worry...you cant find many good hotel, if your travel budjet 20-30 per night, you can rent room in Barcelona. My girlfriend and i spent 8 hours to find hostel by 20-30 euros in Barcelona downtown, it was unpossible. On Ramblas and placa Cataluna the cheapest hostel is 60 euros for the room which you share with minimum 4 people. Very durty and noizy, it is unpossible to sleep there an hour...I found my room for rent through loquo,here is the contacts of the landlady,while you will be searching the apartment for rent, you can stay at one of her rooms (separate) in the city centre by 20 euros:
