Mellow's place was perfect for us. It's a beautiful, modern apartment in the middle of Porto - very close to cafes, shops, restaurants, parking, and tourist sites. He was quick with his responses and tried to address any issue or questions we had. I especially enjoyed sitting outside on the balcony in the evening (there are little balconies with patio chairs and tables outside the bedrooms and outside the kitchen). We would definitely stay at Mellow's place again.
