Belinda's place is great! Although it would be helpful to know that it is located on the 4th floor, the climb posed a minor problem for my family.
The whole place was very neat and cosy! The noise level at night is minimum. However, the aircon is not very cooling in the daytime so I would suggest taking the fan from the bedroom. This would be important to take note during the hotter months. Other than that no issue.
Everything was provided and even little notes were pasted around the apartment to remind us of things such as the trash collection time. The best past thing is that there is a supermarket very close to the area and it is good for the budget! :D
If I were to visit Madrid again, I would definitely book with Belinda!!
