We are very glad that we chose Lugaris Rambla for our stay. The place was very nice, clean, and very comfortable in terms of space, especially being a family of four with two teenagers. My kids had separate beds (my son slept in the convertible sofa in the living room and my daughter in the second bedroom). Having two bathrooms was priceless. The area of Poblenou was very lively, although 10 mins away from the center of the city on a cab ride (we decided to splurge and not the the subway, but heard that the subway is very close and fast).
The day before arrival, the hotel called me to the U.S. to give us instructions for when we would arrive. They do not have a lobby at this Lugaris, nor they have phones connecting you to their reception, so I had to make international calls from my cell to communicate with them. These details were not great and the only reasons for us to rate it with 4 stars. However, whenever we requested support, they did not take long to come and take care of us. They also allowed us into our room earlier than the original entry time, which was very nice. And they sat down with us to help us plan activities, just like any hotel concierge services. We had a small problem with one of the showers and they took care of it very quickly.
We would definitely stay at this hotel again! I am very glad to have read the reviews, this was the reason why we chose this hotel, and why I am including our own comment today! Hope it helps other families!
