I was staying here for a week, coming for a business trip, with my wife, who was on vacation.
Although we didn't get to meet Beppe in person, he was always available by WhatsApp and email, replying almost immediately to all our enquiries. He was very kind to arrange a late check-in for us (with his friends passing the keys), and also provided receipts for the Barcelona tourist taxes, which we appreciated. The place was equipped with everything we needed for spending a week comfortably: towels, shampoos, amenities, linen etc.
One small drawback, which we didn't notice while booking, it the absence of air conditioning, given an unusually hot June 2017. At the end, it turned out not to be a big issue, as we've spent most of the time during the day outside of the apartment, and in the night we used a fan, provided by the host. Still, this is something to keep in mind if you don't tolerate heat and plan to visit during Summer.
This apartment has a great location, 3 minutes walking from a metro station and about 40 minutes from the city center (Plaça d'Espanya). It also has a fully equipped kitchen, which is great for cooking and eating at home. There are plenty of small supermarkets nearby and a Corte Inglés in about 20 min walking distance. The neighborhood is nice, and the place is in a very quiet location, despite being close to a big street.
Overall, a great place and an awesome host. I will consider staying here in my future visits to Barcelona.
