We were at Pep's apartment for 1 night. The apartment has amazing location. It's nicely decorated and have everything you need, both for short-term rent or staying for a long-term period.
You literally live in penthouse (apart is on top of the building), you have your own HUGE veranda (sundesk) with beautiful views to part of Sagrada Familia and Recinte Modernista de Sant Pau from the top.
Location is very good. Close from Sagrada (10 min walk), subway (2 min walk), caffe/24shops/etc (Avenguda de Gaudi street starts right from the house). It's not noisy.
Pep and his friend Alfonso was very welcoming. They answered all our questions (we had only few), was always available to contact, and very kind.
Highly recommend this apartment to everyone.
