This apartment is absolutely perfectly located - it's literally next door to a supermarket, a block away from quite literally the most beautiful building in the world, and within 40-minute walk of the beach. No matter where you want to go to you can hop on the metro (two blocks away) or walk. It's a beautiful city to get lost and walk around.
The flat itself was great - lovely and cool, didn't actually need the air-con all that much. Has everything you need, we were there for a week and felt right at home. Everything was clean and tidy, a vast variety of towels and bedsheets!
We didn't get to meet Pepo but check-in was easy and he was very quick to answer any queries. And listen to his recommendations, they're great!
It's up three flights of stairs so this might be a problem for some but was fine.
it does have a balcony, but not really big enough to do anything on (other than hang up washing!) and it doesn't get much sunlight, just a bit in the mornings, so if you want a lot of sunny outside space then I wouldn't recommend. However the flat itself is lovely and light and airy and the doors open up fully which was gorgeous in the evenings.
Would happily recommend a stay here to anyone who wants to be in the heart of Barcelona.
