We had an absolutely great time in Porto and staying at Diogo's apartment. The location was fantastic and the views of the city and river were spectacular! The apartment was very well maintained, clean, and had all the amenities you would expect. We appreciated the bottle of port wine, coffee, tea, etc that were provided for our stay!
I will warn you that Porto has an extreme topography with hills, inclines and stairs everywhere. However a visit to Porto is well worth the unexpected exercising I got while exploring the city! Thanks again Diogo for opening your apartment to us!!
