We had to unexpectedly extend our stay in Madeira due to the flight situation and we booked The Design House until we were able to return home.
The house it's self is really comfortable and feels very homely. The kitchen is well equipped and the location is great. There were only 2 of us but the house would comfortably sleep 6 adults and a couple of children without feeling like you were on top of each other. There is easily enough seating/dining/sunbathing space to accommodate those numbers and board games/PS4 are provided. Only the TV could be upgraded to a more modern smart TV but if you're on vacation, you wouldn't be wanting to watch the TV too much.
The view over the banana plantation to the sea beyond is beautiful and the house is located at the end of a no through road so it is very quiet. It's within relatively easy walking distance and a 2 minute drive to Calheta beach/marina where you will find some lovely restaurants and general grocery shopping etc. It's also 2 mins from the highway where you can reach Funchal within 25 minutes.
The pool was great, we paid for the heating which was reasonably priced and it was comfortably warm enough to swim even in January. In other homes we had rented before this one, the pools were not heated and ranged in temp between 12 and 16 degrees......
Vanda the house keeper was very nice and available on WhatsApp if we needed anything.
The only negative about the house was that there was virtually no phone signal and the internet speed was not great. As we unfortunately had to work while we were there, this caused us a problem but if you were staying at the house on vacation, I think it's certainly something that you could live with.
