Marc's place was great.
It's located not too far from the the airport by taxi but also easily accessible via the metro connection too.
Had a bit of a hiccup with the address but Marc texted us with the correct details.
Arriving was simple enough, dropped off by a taxi and Marc was waiting for us at the apartment and showed us around and gave us a couple of maps and few tips.
The place itself was very clean and a a good size for a couple but getting 4+ people in may be a bit of a squeeze!
Kitchen had all the usual amenities including fridge/freezer, electric cooker, microwave etc. and a small table for four but it had a few extra chairs.
Bedroom had a double bed and then a separate 'overhanging' bed above which is accessible via a ladder.
Sheets were a bit thin which was not a problem as we had warm evenings but a spare blanket would have been good if the weather did turn.
The lounge had a comfortable sofa and large tv for those evenings after a long day of walking!
Bathroom was nice but the shower may be a little small for some.
All of the 'negatives' above had zero impact on our trip and it's merely constructive criticism for others.
The location itself is pretty good. It was really quiet at night even though it's on the ground floor. The place is close to three metro stations, the tram and even the Camp Nou is just a 10-15 min walk.
We loved Marc's place and we would definitely stay again next time we're in Barcelona :)
