Marina and Ramon's apartment is located a short walk from the Metro, which is easy to use to explore Barcelona. The Sagrada Familia is astounding and a unique sacred building with philosophical nuances etched into every aspect of the structure. The Sagrada is a short stroll (15 mins ) from the apartment and the walk takes you along the Avinguda Gaudi, which is a pretty avenue and with a plethora of inviting restaurants etc. The Hospital de St Pau is also worth viewing and close to the apartment. Also Parc Guell is a 15-20 minute walk (uphill) and well worth a visit. We even managed to spot a Hoopoe scavenging in the undergrowth there.
Marina's apartment is in a great location. It was spotlessly clean and perfect for our stay. The two terraces would be perfect in fine weather. We had a great 4 days despite the rain etc.
Thank you very much Marina and Ramon.
