This is a great place to stay in Barcelona. The studio was complete and clean; there is a big shower stall and very nice bath towels to use. The terrace was a delight and we used it every morning and every evening. You can see on the BNB web for her studio that the bed is a couch. Of course, we knew that beforehand, and the sleeping was not too bad at all.
The location was very good. A few doors down, there is a convenience store where we bought wine, liquor, snacks, and even a bag of ice for the small freezer compartment of the refrigerator. The bag fit fine, and it was all we needed for our 5-day stay.
We walked about 3-4 blocks to Placa Catalunya for our hop on bus, and it was a flat walk. It was there that we found a great restaurant, where on Wednesday and Sunday, everything is 1 euro ~Cerveceria 100 Montaditos on Rambla, just after Placa Catalunya.
We would recommend Marita's studio to any couple. The studio is on the 5th floor, but there is an elevator that takes you to the 4th floor, and that was fine for us. We loved the rooftop!
