Casa do João da Eira was hands down the best vacation home experience I've had. Rui met us at check in to greet us and show us the property. It was well-cleaned and everything had been thought of--fresh handsoap in every bathroom, towels, outdoor fireplace prepped, and a bottle of Madeira wine and a bolo de mel cake for us.
The property is amazing. It was cozy for just two of us, but would easily accommodate 8 people. The water heater is even tankless, so nobody gets a cold shower. Every floor of the house has a view--the beds in the attic are the only ones you can't see the sunrise from without getting out of bed. The ground floor has the kitchen and a generous living room, as well as a half bathroom. The ground floor terrace has several tables and chairs to use while cooking on the outdoor fireplace--not to mention the gorgeous view. And, yes, you really can see a waterfall through the kitchen window while sitting at the table. Upstairs there are 3 bedrooms and two full bathrooms. The master bedroom has a balcony with an even better view than downstairs...and two cozy chairs and a light to enjoy at any time of day or night. The attic has twin beds and a slightly separated snug area with couch & tv.
Rui was incredibly responsive, giving us great restaurant recommendations and making sure we had everything we needed. He was very welcoming & friendly, and his daughter, who helped check us in, was as well. The town of Seixal is beautiful and has a beach as well as tidepools to swim in--we were there in January so didn't go swimming, but even then the water was warm.
If you're looking for a beautiful, relaxing vacation stay, I can't recommend this place enough. We're already hoping to return!
