Elói and Miguel are great hosts! They were always easy to contact and very helpful providing us with great suggestions for restaurants, bars and nice places in general. They even printed our boarding cards for the flight back home.
The studio is small but comfortable and perfectly located to enjoy the centre of Porto since everything seems to be within walking distance. Furthermore, the bus to the beach and many other nice places (and even the airport) leaves right in front of your door.
It should be noted that it can indeed be a bit noisy outside during the night and the bathroom is quite small and cramped. Also the kitchen facilities might be a bit limited for those wishing to cater themselves.
However, we would still recommend the studio and really enjoyed our stay!
