This apartment is exceptional. You can't beat its location, the space available inside, and most of all, you can't beat the hospitality that accompanies it. Silvina was incredibly communicative and helpful leading up to our arrival. She was unable to be there when we made it to Barcelona but her colleague Ivan met us at the apartment; Ivan was so gracious and helpful, spending time with us to go through the apartment and also share with us some things to do and places to eat while we were in town. Check in and check out were so easy.
The apartment is about two blocks away from the L2 metro line (Monumental station), which was just a few stops away from a transfer station. The apartment is also a short couple of blocks walk to Sagrada Familia. We were right around the corner from a market that had basically everything we needed during our stay, and several great restaurants were within walking distance.
The apartment is huge. Perhaps it felt that way because there was just two of us, but even with additional people I can't imagine feeling cramped. There are two good sized-bedrooms, a huge closet/dressing room, a "family room" of sorts with a TV and comfortable couch, a dining area, plus kitchen and bathroom. The kitchen has the necessities you need to make dinner including tons of pots and pans, silverware, dishes, and glassware as well as staples like olive oil, salt, and pepper. The half fridge was the perfect size since we went to the market everyday and just bought for that day. There is a Nespresso-type coffee maker plus an electric stove that I battled with personally, but I'm used to gas so that's on me. Wifi signal was great and there's a washing machine/clothesline if you need to do laundry. The building was secure and in what seemed to be a good and safe area.
Overall, I would highly recommend this apartment and would absolutely stay here again if we find ourselves back in Barcelona. Thank you to Silvina and Ivan!
