I booked a room for one week at Emilia's apartment and loved staying there. Emilija is very great host, gives you advice and tips if it is your first time in Barcelona. She made my stay very comfortable in spite of my complicated check-in/check-out schedule.
The location was very perfect for me to attend meetings at the Fira Gran Via or even to go to the centre of Barcelona, thanks to very good transportation facilities around (a lot of buses, metro stations, and Plaza Espanya as a central hub very close).
The room in itself was small but clean and enough for one person-one week-stay. The apartment is exactly the same as appearing on the pictures, very well-equiped and comfortable. There is even a balcony.
I highly recommend staying at Emilija's place and will come back again for sure.
