Sandra's place is at perfect location! At Gran Via and close to everything. It's on 4th floor with no lift, but we don't mind at all as her place is really cosy and welcoming. Sandra is a very warm and friendly person, we enjoyed her company in the evening and chatted quite a bit.
The tako shop at ground floor has really valuable and delicious food. Other than that there are so many restaurants and shops around and we regretted for not staying longer in Madrid.
