Wally's apartment is beautiful, it looks exactly as it appears in the pictures and is so clean. It's well equipped and comfortable, the air con ensured we were kept cool in the lovely Barcelona sun! The balcony and roof terrace were both an added bonus to our stay.
The location is within walking distance of Sants station, which has great links to everywhere else in the city, and there are a couple supermarkets nearby for any essentials.
Wally also gave us some great tips for sightseeing, he was incredibly helpful and communicative, and really nice about us breaking a glass.
I'd recommend this apartment to anyone visiting Barcelona.
