    Shame the indoor pool is not free for the persons staying at the hotel and shame it wasn’t specified before booking…

    Liked the hotel, the rooftop pool and the surroundings. The room was spacious and had everything we needed.

    Breakfast maybe could have had different options interchanging. The pillow guide was nice but they are all huge and the bed options should have a queen or bigger as it was difficult to sleep as a couple and also hold the large pillow.

    Friendly staff, great location. Spa and amenities were nice also. Room was cleaned often and well. Nice breakfast and assorted fruit. Loved the pillow guide. Love how walkable the area is and close to mall!

    One of our rooms was an older style with a bathtub but still perfectly comfortable and clean. The hotel decor is a little dark and full of wood. But this was not a problem at all!

    Great location to explore Barcelona and go to the beach. Restaurants nearby and rooftop pool with a view. Really lovely staff who were so kind in helping us celebrate occasions with Cava, cake and sweets for children’s bday too. The breakfast was delicious too.

    Nice hotel, shame there was no access to the beach close to the hotel, so probably 10 minute walk

    Selection of cereals wasn't great, in particular lacked muesli / granola. disliked the glass window between bedroom and bathroom, even with blind pulled down light shone between the two rooms. All light switches were clearly labelled unfortunately one light was controlled solely by the Air Conditioning controller , very odd and we needed to go to reception to find out how to turn the light out. Could have done with a few more loungers by the pool.

    Good selection of food at breakfast including very nice fruit. Hotel room was spacious and clean and decor looked reasonably fresh. Didn't use the gym but appeared to be very well equiped.

    Some little bits of the room could do with a little touch up, few scuff marks here and there, just a couple of bits that could do with a little attention and it would be up too standard! Couple of the light switches needed a little attention too. Also during our stay we had water start to drip through the ceiling from upstairs. To be fair, we let the staff know and they were prompt at helping us, dry up the water and get to the source of the water source. Staff were friendly and helpful considering it was very late at night/early morning. I will say our little leak issue was not the fault of the staff who work there and they did there best at resolving the issue given the circumstances. :)

    Very good location especially as it right next to a tram stop! Very good room as we had a suite. Nice size room, with alot of natural light coming in.

    Hotel starting to show its age. A few little disappointments. Toilet brush fell apart. It had been glued back together. Asked for new one but not replaced. Toilet running constantly after flushing. Sink tap loose. Small things but dissapointing.

    Rain shower head pressure was very bad, safe in the room was broken. Booked a twin bed, was given room with a queen, needed to go request change. Terrace closes at 23:00, bit early. Some of the bar staff had issues understanding basic English.

    Room, breakfast and facilities were all good, with a few exceptions.

    The receptionist was rude and inattentive, making us wait for 10 minutes while busy with other tasks. Initially, he refused to provide a double bed for us as a couple, only giving in after persistent requests. Such poor service is unacceptable for a hotel aiming for good reviews—guests come to relax, not deal with disrespectful staff.

    The hotel is in a good location. The rooms are spacious and comfortable.

    The door knob broke during our stay, it can't be opened from outside, and the staff cannot fix it promptly. The check in process takes too long, we waited 40 minutes in the queue.

    The room is very spacious, the toilet facilities are very clean. It's located right next to a tram station.
