What a great place! This is where you want to stay! Middle of everything. Easy access to the entire city.
The check in process was flawless and went exactly as stated. We landed at BCN grabbed our bags and a taxi. We then called the number and when we arrived David was there to greet us and show us the apartment with explanations of everything and some suggestions of nearby supermarkets and restaurants.
We loved this place.
The one feedback that I give was the wifi and the TV were super slow. The wifi is important for people out of country without mobile data. It helps to plan the next day and see whats in the area, etc. We reset the router/modem but was very slow. Dial up slow. The TV was spotty and super slow too, seems like it was on the same line. The TV wasn't a big deal tho.
There is a great supermarket within 1 block. We cooked breakfast every morning. Everything you need to cook is provided. There is a large enough refrigerator for everything you buy.
When we were leaving David was able to reserve us a taxi which showed up right at the front door and right on time. A great service vs. flagging one down and not knowing if you're going to get a good taxi.
I would stay here again for sure.
