We loved our stay in Porto and in this apartment. It's in the prefect location in the heart of the old town. Two minutes walk from the iconic bell tower and just a short stroll downhill to the Douro River. Also a few minutes walk to the railway station. Plenty of restaurants very close by including a few in the street. We'd also recommend Mercador or Floresta cafe on R das Flores for breakfast. Also excellent pizzas in Il Pizzaiolo on R de Candido dos Reis. We also found ourselves enjoying a late afternoon drink in Aduela bar on R Das Oliveiras.
The apartment itself is perfect and the balcony a real plus. Highly recommended
