The hotel is perfectly located near plaza Catalunya, which is also the last stop for the airport-shuffle called Aerobus. You're close to the main street La Rambla and several subway-stations that can take you anywhere you want to go (Sagrada Familia, the beach etc.).
It's not the prettiest hotel I've seen, but the facilities in our room were very good (New TV, new hairdryer, Nespresso coffee maker) and it was very clean. The staff is very nice and helpful, and the breakfast is amazing!!
Next time I might try another hotel in the H10-chain, but I would definitley recommend H10 Universitat.
