Beautiful apartment, conveniently located steps from the metro. Walking distance to Sagrada Familia area. Germain was very accommodating and allowed us to leave our baggage in the apartment before checkin time.
We visited Barcelona in July and it was HOT. The apartment does not have air conditioning and can heat up pretty quickly. There is a breeze that comes through but can be rather uncomfortable if you're not used to dealing with humidity. We ultimately had to book a hotel for a couple nights to escape the heat.
Overall, great stay minus the the heatwave.
