We stayed at Casas da Biquinha as a family of 6. It was wonderful. Maria was a great host, very kind, helpful and professional. She met us upon our arrival and made sure we were comfortably settled.
The apartment is great, nicely decorated, clean, tidy and with everything we needed. The location is excellent, in the center of Sintra historical center.
We had a great experience and definitely recommend Casas da Biquinha to other travelers.
