I approached this stay at Ramblas Hotel with trepidation, after reading the mostly poor reviews on here.
Well, we had a great time! We had room 409, a double with a small balcony overlooking Las Ramblas. It was nothing fancy but it was clean and comfortable. There was a safe and a fridge. It even had a bath as well as a shower and loads of hot water. No tea and coffee equipment but we knew that.
We were not particularly aware of noise from the street. Yes you could feel the odd rumble of the metro and now and then a door slam but it did not affect our sleep. Probably the 2 thick layers of blackout curtains helped (they certainly kept it nice and dark at night!)
Breakfast was ok....cereals, fruit, yoghurts, ham, cheese, pastries, cake, bread...and on request, gluten free bread and biscuits for me.
The lifts were small and quite slow, but that didn't inconvenience us. The whole place is an old, characterful building with faded charm.
Location wise it was excellent, the metro (very easy to use, we bought a T Familiar which gave us 8 journeys for under 10 euros) was less than 5 mins walk. It was also walkable to the harbour (30mins) and the Gothic Quarter and Bouquera market (10mins). Do try the nearby Placa Reial, a lovely place for eating outside in the evening (even in March as the bars had outdoor heaters) and beautiful in the day too.
We had a lovely time.
