Miguel's place is in a perfect and conveninent location to explore old city Porto. The flat was clean, didn't smell, and had all the amenities listed. The minor details of the space could be better looked after (ex. loose sink faucet, toilet runs occasionally, etc) but for our purposes and for exploring the city it's great value. The Wi-Fi works well, the shower stays hot for two 10-min showers, the bed is comfortable, the host is exceptionally responsive, and the flat was perfectly clean.
There is no central heating or A/C but a space heater and fan are provided. If you're prone to being cold and expecting to spend a decent amount of time in the flat, be aware that the space heater isn't really sufficient to heat more than a small, personal area. If you are self conscience, it's worth noting the authentic and beautiful wood floors make a decent amount of noise in some spots.
We really enjoyed our stay! Would recommend for those who are low-maintenance and seek a perfect location.
