Had an amazing stay in Nicolas apartment in Poble Sec. First of all communication was impeccable from the start! He messaged me a few times before the stay and even during to see how it was going. He offered us a wine bottle at our arrival and gave us a little briefing about Barcelona. The apartment was clean and spacious (exactly like in the pictures). We were 4 and didn't feel crowded at all. Plus the balcony is a great part of it ! Would recommend !
