Stayed for 9 nights in Sept. Benefits of Hotel are the location which is not central but well connected due to the metro just around the corner. Being one street back from the busy and noisy Gran Via means that these rooms are quieter than others in the area. The rooms were clean but simple. No Wifi connection in the rooms but LAN cables available at the reception.
Room service was lacking, note to self: next time check for a bath towel before taking a shower.
The air conditioning is old meaning it has three levels but no room temperature setting.
Use of room safe costs!

my friend and i have just spent 5 fantastic days in barcalona! never been before but will return for sure!!! managed to cram lots of sights into our trip, lots of shoppin and still time for eating, drinking, and sunbathing!! the hotel is ideal for being close by to restaurants, shops and the local bus routes to las rambles but not close enough so you are disturbed by the busy nightlife in the early hours, very clean, staff helpfull and speak english, breakfast suited our needs just fine, would stay again at the hcc open xx

My Boyfriend and I spent a fantastic four days in Barcelona. We managed to cram everything we wanted into that time even in the August heat.
The hotel was well located to reach all sites. It was 10 minutes walk from the Olympic park, 20 minutes walk from Las Ramblas, and close enough to the Nou Camp. It was clean, the breakfast was adequate (though no hot option) and there was a great restaurant 10m from reception.

My wife and I spent an amazing week in Barcelona. Of all the cities I've visited it was the most interesting and maybe the most beautiful.

The HCC Open was a perfect compliment to the holiday trip. The hotel was clean, well run and well located.

We walk when we are on holiday and the HCC Open was an good distance from the Ramblas. Since the buildings and gardens of Barcelona are wonderfully different and beautiful walking through the city was a big part of the holiday.

The day began with a very good included breakfast which usually included Spanish dishes as well as typical European food.

The beds were firm but above average in my experience.

The only knock on the place, their in house laundry service is the most expensive I've seen in a long time.

As I said in the title, I would return to Barcelona and return to HCC Open.
