Very easy stay with David. Apartment easy to find and very close to the Glories metro system and a short walk to Familia Segrada.
The room was clean and bed was comfortable. This is very cheap accommodation and ideal for a tight budget. It is a bed for the night and somewhere to return and shower before heading out into the city again. I didn't use the kitchen as that appears to be David's private space, so this is a B rather than a B n B !
