My husband and I loved staying in Roberto & Elisenda's flat! It is exactly as described. A lovely, quiet street in a very convenient area of Barcelona. Not far from the Metro and lots of attractions. Plus, just a nice neighborhood, not too touristy. There are good, reasonably-priced little shops and cafes nearby. And with the kitchen at the flat, it was very easy to go to one of Barcelona's famous mercats and pick up great items for a meal. I might have liked a drip coffee maker, but that's the "Ugly American" in me, I guess (I love espresso, too, just sometimes need my cup of Joe).
It was a little hot in the apartment with no A/C, but it was July, so not unexpected. And great to have reliable wifi, and a washing machine. All in all, a wonderful experience, which we would definitely do again!
