If you are coming to Barcelona for the architecture, then the Barri Gotic Quarter, also known as the Old City, is an ideal destination. Not only, but it also has some excellent accommodation options. However, they are quickly taken. If you are looking for a cheap place to stay, better make an early reservation. Otherwise, you may have to splurge.
There are no better views of Barcelona than the one you get at the top of the mountain in Montjuïc. Full of tourist attractions and sightseeing possibilities, this barrio is excellent for the lovers of clean air and lovely neighbours.
Accomodation ranges from 30 euro to over a hundred per night. Here, you can find the Magic Fountain of Montjuïc, the Poble Espanyol, and the MNAC museum. A short walk away from the hill is the Barcelona Olympic stadium.
