Beta De is very well located in the raval diactrict and very close from the ramblas. Its a cozy little room with two comfortable beds and a small kitchenette. The windows fall on the street side and are a little noisy by night but not till very late by Barcelona standards.
The bathroom is sufficient and very clean.
Mikel himself is extremely friendly and helpful. He did his best to make us comfortable and even taught us how to make a Pallea.
If you want to live in the heart of the city and walk all over this is a great little spot right by the MACBA - contemporary art museum. Easy access by bus to the airport as well.
