Josefa's accommodation is very well furnished and very clean in a lovely central location. Most of the main attractions you will want to visit in Porto are within walking distance from the accommodation. Josefa supplies things like a washing machine, iron and mini iron board, there was even a hair dryer with a diffuser for curly hair ( my girlfriend was surprised and happy).
Josefa herself communicates very very well and was happy for us to check in early and check out an hour later. She also gave us lists of places to visit and a map to use.
Overall my girlfriend and I had a very pleasant time at Josefa's place.
