Highly recommend this place! We had a really great time in Jaume & Marta's studio. The location is just perfect, you'll be right in the old town with a number of nice cafés, bars, restaurants and sights just around the corner (actually, Espresso Mafia, known for the best coffee in town, is literally just downstairs. You should also check out Brots De Vi on the other side of the street if you're looking for wine and/or delicious food). There are (at least) two supermarkets nearby.
The studio itself is awesome, too. We loved the interior and, as everyone else mentioned, it's super clean. Unfortunately, we didn't meet Jaume and Marta in person, however, check-in and check-out were super easy and Jaume answered any questions instantly. Thanks for the wine, by the way!
