This is a really special host and space. I originally intended to book elsewhere but I botched it. I booked Estela's place on a Sunday night, while on the train from Paris. She was incredibly responsive. She even offered to come pick us up from the subway stop nearest her place at 11 PM at night.
Estela's location is in the hills\mountains to the west of downtown. Please note that she indicates in her description that her place works well for people who have a car. I agree with that. We rented a car in order to get to her place and for other reasons -- e.g. I knew that we wanted to go to Girona, Park Guell, Sagrada Familigia, etc. The arrangement worked out superbly.
The location is beautiful. It is on a hillside with a beautiful view. It is close to Temple of the Sacred Heart of Jesus ( a big church ) on the top of a mountain overlooking Barcelona. It is *quiet*. The last time we were in Barcelona we stayed on La Rambla and it was both noisy and brightly lit well into the night. We loved the quiet of Estala's location.
The space itself is clean and charming with an outdoor patio with table and chairs where you can sit and drink your coffee, looking out over the valley. The whole thing is classy with beautiful tile all over the place, especially the bathroom. The AirBnB space is completely separate from Estela's, meaning that as far as I'm concerned it is like an apartment. The space will accommodate three, but is probably best with only two.
Estela has a number of 8.5 x 11 laminated cards with various info on things to do, including hikes in the local nature reserve. The info cards are very helpful.
The WiFi was weak while we were there, but to be fair, I did not bring that to Estela's attention. It's possible that there is\was an easy fix. Connectivity on my mobile was weak, both when roaming on my Verizon service ( U.S. ) and when I replaced my service with LycaMobile ( Spain ).
We had a great, great time and would stay here again.
