Previous arrangements worked out very fine. The appartment is located very central, perfect to explore the city by foot. Around really nice bars, restaurants and cafés. Sadly the room was in generally quite wet and therefore a bit of mold on the cealing and the windows. We weren't good enough informed about how to use the air conditioning to manage it. As we tried it didn't worked out. We realized the whole situation existed because of the climate in winter season, not because of the appartment. Although it was very cold and only one little heater worked. It would have been nice to be informed about the situation earlier on because we had two allergic people with us and it wasn't comfortable.
The bath/kitchen were equipped with everything we needed. Concluding, Porto is maybe a little more recommendable in summer, though we had 4 out of 7 days mostly sunny weather.
