This place is great!
I stayed here for about a week and a half and never got bored It's in a quiet neighborhood which is about 6 blocks away from Plovdiv's wonderful walkable Old Town. Every day I'd wake up to the sun, walk to a nearby cafe for breakfast of Баница и Айрян (Banitsa and Aryan, traditional Bulgarian breakfast foods, it's a puffy cheese and egg pastry and a yogurt drink, and I miss it every day). Then I'd walk down to the Old Town and spend the day in the shops, museums, roman ruins, etc. I was lucky enough to be there during an art festival, so there was a ton to do, but it seems like the downtown area is always having plays, festivals, concerts, etc.
For the apartment itself, it's simple but clean, with a really hip look. there's cool art, two beds (one a daybed, one a futon) and a little kitchen.
I'd stay here again if I came back to Plovdiv
