Stefan and Antonio were very helpful and alway around to answer our questions. they spoke very good english and were very patient with our questions throughout our stay.
The apartment was in a good location on La Rambla, however because of that you will get people passing through the street below the apartment constantly and as it's located opposite McDonalds you will get drunken crowds during the night on a weekend, but this goes with any city centre location so you got to have this in mind if you want convenience.
The apartment was brand new and very clean, the size was generous and with a stylish design, the hosts were kind enough to provide us with amenities e.g. water, coffee, milk and even a bottle of wine so we didn't have to run to the supermarket immediately, there was also a full set of toiletries and slippers for us which was thoughtful.
Overall we had a very happy stay, we were able to hop back up to the flat for a quick refreshment whenever we wanted and then get back to the action without travelling too far, would recommend this apartment if you want to be in the centre of all the action in Barcelona but enjoy a quality environment to stay as well.
