We booked this having had our original apt cancel, but we couldn't have been happier with the place! Great location within 20-25mins walk of most things we wanted to see & do including many incredible bars & restaurants, gothic quarter, gracia, sagrada familia.... Some street noise from nearby bars but not a very touristy area so not too bad.
This is a very large apartment with 4 separate bedrooms, 2 with juliet balconies & a large terrace. Very well equipped, simply decorated & within a few minutes of 2 bigger supermarkets with several smaller shops within seconds, use the supermarkets if you can though as they're significantly cheaper! Taxis are very reasonable in Barcelona so for us worked out cheaper than 4 metro tickets, when our legs couldn't carry us any further!
Really helpful & friendly desk staff too (you collect the keys from the office a little way away) they even called a taxi & gave us a 10€ voucher unprompted.
Overall a great visit.
