We had a wonderful 5 night stay in Barcelona at Picasso Suites. We really enjoyed the rooftop terasse and the awesome market next door (Mercat de la Concepcio). The space feels safe and is modern and clean with 3 bedrooms and 2 bathrooms. Everything a person needs is there and around, multiple cafés, shops and restaurants. Being in the city center, there is always some noise, but we all slept very well.
You can walk to Sagreda Familia, la Rambla, the Gothic Quarter. We took the Metro (very easy) to Montjuic and Parc Guell.
Communication is easy once there and service excellent.
We would certainly recommend staying here!
