This place was absolutely perfect! It as in the most ideal location. When I saw online that it was centrally located, I was concerned this was not accurate, but it could not have been more true. We were steps away from Placa Catalunya which is the hub for the Aerobus, tour buses (we did the double-decker hop-on-hop-off; highly recommended to get the lay of the land), cabs and the beginning of La Rambla. Everything was walk-able. The only time we could not walk was to Montjuic for the Magic Fountain and Park Guell (which could have been done on the double-decker bus but we ran out of time so we went back).
The apartment says 3rd floor. We were expecting two flights of stairs but it was 4 flights. We knew it was not on the third floor but did not know the conditions of the stairs. Be prepared to climb 60 steep and very narrow steps. For the most part it was fine; luggage was a little more difficult.
The apartment has everything you need. It is exactly as advertised. All the pictures are accurate and the all described amenities were in place. Barcelona proclaims itself as a WiFi city but we found the best, most reliable WiFi was in the apartment. The hosts have thought of everything you will need from a guide book written by them with anything you may need to know as well as itinerary suggestions. Once we figured out how to use it, there was a Nespresso machine and coffee supplied! If you are American and love your Dunkin Donuts, just know the coffees are much smaller and it took us some time to find a large coffee like we are used to. Even if you order Americano coffee, it is not what you are thinking.
The only downfall would be that we could not check-in at the previously agreed upon time. We were supposed to check-in at 2 and after an overnight flight and being up for 27 hours, being asked to come back at 3 was not ideal. We were exhausted!
I highly recommend this apartment if you are interested in staying somewhere that you can walk to everything you need and to live like a local and have that Spanish feel. The hosts were super-helpful with quick responses anytime we had a question or needed anything.
Thank you!
