Roberto's apartment was ideal for our trip. The subway was a 2 minute walk, Placa Espanya a 12 minute walk. The apartment was as shown in the pictures. Very clean, well organized and enjoyable to stay in. Unfortunately it rained a lot while we were there, so we weren't able to enjoy the patio. I think it would have been really lovely out there in the sunshine.
The apartment had all the equipment we needed and more - dishwasher, microwave, washer. The best was the Espresso machine! We were living it up!
Others have commented about the stairs - there were a lot, especially when we had the suitcases to take up. So make sure that you are ready for the stairs (they do allow you to indulge in sweet treats!) and that you pack light.
We recommend Roberto's apartment and hope you enjoy it as much as we did.
