The hotel is lovely, well clean, and the rooms themselves are great. The staff is phenomenal: everyone is super helpful and friendly, definitely the biggest highlight in my opinion.
Location wise, it's right next to Palau Guell and La Rambla, so it's right in the center of the city and close to everything you need.
However, the sound isolation in the hotel is very poor, and you can hear everything the other guests are doing at any point. So if you are a light sleeper or easily bothered by noise, this might be an issue.
Everything else is great, the price/quality ratio is very good overall. Recommended, but keep the sound thing in mind.
