My husband and I stayed in Xavier's private room for one night before we left Barcelona for Sevilla. Xavier was out of town for business, but Sergio took great care of us. He provided clear explanations of how to access the building and of the house rules. These were simply to respect the space, other tenants, and the neighbors - totally reasonable. Our room had a private bathroom, was clean, and we had no problems with wi-fi during our stay. We checked out very early to catch our flight the next morning. Our time here was short, but I would recommend staying here to anyone looking for clean and affordable housing in Barcelona.
