Estela's apartment is a beautiful space in a beautiful location. Inside, it is quite small, with a tiny kitchen nook, but perfect for two people, and very nicely appointed. Outside is where you will want to spend most of the time, either on the patio in front of the apartment, or by the swimming pool at the back of the house. The apartment is well located for hiking in the hills, and there are two restaurants within walling distance (15-20 minutes). We did not try those, but we did follow Estela's advice to order in a paella, which was excellent. Estela and her husband were very welcoming. We had a bit of a hard time communicating on the day of our arrival, due to our lack of a local data chip. We missed the train we had promised to be on, and so it took a number of efforts on Estela's part to find us. We were relieved when she finally did and took us in cheerfully despite all the hassle we had created for her. On one of our days there, I went into Barcelona by public transit. I missed the bus, so I walked down the hill to the train station, which took about 20 mins. From there, it's only 10 minutes to Gracia (a very nice area with few tourists) and a few more to Placa Catalunya. On the way back, I walked back up the hill in 30 mins - a very pleasant way to get in a bit of exercise (though you wouldn't want to do it with luggage!). All in all, a great place!
