Location, location, location: Nestled in a quiet area, this comfortable home was ideal in so many ways. It had all the amenities of home and great wifi for planning your days trips and meals. As per this PERFECT location...while the highly developed and extensive metro system was literally a 2 minute walk away (Plaça de Sants), if you are a family/individual that likes to walk, some of the major attractions are less than 2km away. Plaça d'Espanya was a 15 minute walk; check schedules because dancing waters are Thursday, Friday and Saturday. From there you can take a series of escalators for a 2-minute ride up to the Museu Nacional d'Art de Catalunya (MNAC)...which is free on Sunday's after 3pm. From there, you can take a couple of more escalators up and a short 15 minute walk up to Montjuïc Castle (also free on Sunday's after 3pm....we discovered this by chance). Train station (Barcelona Sants) was 10 minute walk; we took two day trips, one to Monserrat (great mountain hiking...very high) and to Girona by high speed train (Charming old town/Game of Thrones site for filming). Mercat de Sants is a 3-minute walk away and has everything you could need in terms of fresh food and groceries; we cooked our own breakfasts and late night meals in the apartment. Check "Yelp" app or website for quaint, well priced, excellent restaurants in and around Sants (vegan options are everywhere). Addis Abeba was a great little Ethiopian find a mere 8-minute walk away.
In terms of the apartment, everything was great. There was a minor issue with the "on demand" hot water system, and Angels was quick to send a technician.
By the way, Netflix has a great 2-hour documentary on Barcelona and Catalunya titled "Two Catalonias"...It gives you a lot of insight into the current mindset, pride, culture, and history.
