The Hotel Gaudi is right off Las Ramblas, but I found it to be quiet and safe. (My companion heard some noise, but I slept right through it.)
At first the staff seemed preoccupied and cool, but they warmed up as our stay progressed.
Our room, on the 5th floor, was all right. The beds and bedding are due for an update but seemed clean enough. And if you walk ten miles a day, you'll fall asleep just fine.
Nice deep tub and shower.
But the terrace! Oh, my dears, the terrace is spacious and comfy and looks right across at the rooftop of the Palau Guell, with all-day-long views of Gaudi's whimsical mosaic towers. There are two chairs, a table, a lounge, and a big bench. Wind down with wine and crusty bread and gaze to the horizon, the main element of which is the blue Mediterranean.
We had the 11 euro breakfast one day only. The room was disorganized, the food was lackluster, and the solitary attendant had trouble with the coffee machine. Not at all recommended. But no worries! Sweet little cafes abound where you can start your day with cafe con leche and a croissant for less than 5 euros.
Yes, I would stay again at the Hotel Gaudi.More
