Advantageous location since it's near to a supermarket and two metro stations that'll take you easily into the heart of both Gaia and Porto (both sides of the river).
The house is well maintained, kept clean, comfortable to be in (the heater is very useful in winter), fairly good sound-proof from the outside so you'll sleep well and security is great. Also very cheerful and soothing choice of decoration and colours.
In times of the covid pandemic, hygiene is taken into consideration very well, including use of the jacuzzi which is well maintained and cleansed; the water is filtered and its use is regulated between guests (in other words, no mingling with strangers if you pay to use it so that's great!).
Host is very communicative, helpful and accommodating.
My girlfriend and I enjoyed our stay very much and would definitely stay here again! :)
