I really enjoyed my stay in Janeth's space- the use of space in the room is really efficient; a really good desk/work space set up , and then a really comfy bed that folds out super easily.
The location is on the fringes of the 'tourist' area, so it is really easy to walk to the more central parts of the City and is a few minutes' away from public transport, but situated in a really vibey, more residential local area with a lot of restaurants and at the foot of Montjuic hill, which has many of its own nearby attractions. You get the best of both worlds. If you're looking for value-for-money, are spending a bit of time in Barcelona, and need to work while you travel, I' d definitely recommend staying here.
