If you go to Estoril - stay with Teresa!! The place looks exactly like in the pictures and is decorated with lots of little details that make it cosy and warm. Teresa herself was perfect to communicate with and made everything possible to ensure we would enjoy our stay! Especially on the first day, she took a walk with me and showed me around the town and gave great tips for restaurants etc.
All in all, I would love to go back there as soon as possible and can only recommend this studio for your holidays!
