The room in Sivgin's appartment is an excellent option for budget vacation in Barcelona. On one hand, the location is very convinient, green slopes of Mount Montjuic are at arm's length, while Gothic Quater and La Rambla as well as beaches of Barcelonetta are also in a walkable distance, less than 30 minutes by foot. On the other hand the district is calm and less touristic. You can find good tapas bars for locals as well as many supermarkets, bakeries and grosery stores with a reasonable prices.
But the main advantage of the property is Sivgin's hospitality. As we visited her in winter, it was cold. Especially in the room, which she usually provides for guests via airbnb, so she changed this room for her own warmer room and also provided us with electric heating. Moreover, for a small extra fee Savgin provided us with kitchen with all equipment (normally the kitchen is not included in the offer). Finally, she was very friendly with our daughter, played with her and even gave her a gift before our departure.
So we definitely recommend to stay in Sivgin's appartment. The only detail is that it could be cold in provided room in winter. But it's not Sivgin's guilt.
