The house is in a great location! Just minutes walk to bus, tram and the Douro River. It's also an easy 20 minute walk into downtown. The Continente grocery store is about a five minute walk away.
However, as others have mentioned, if you are sensitive to smells or mold, you may not want to stay with Miguel. I'm sensitive to mold and the house is very musty smelling. I thought I was getting a cold or had COVID-19 because I had a sore scratchy throat, congested and was sneezing a lot. However, all symptoms disappeared immediately once I returned home to Lisbon.
