The apartment is in an ideal location, really close to Plaça de Catalunya (for transport links all over the city) and comfortable walking distance to the Gothic quarter and La Rambla for restaurants, bars, entertainment.
The place itself is comfortable, with a lovely master bedroom and two other decent bedrooms (with 2 x single beds in each). The two showers are both excellent, and kitchen is well stocked with utensils and equipment if you're having a longer stay and want the opportunity to self-cater.
Overall, a great base from which to explore Barcelona, and really good value for money.
