A great location. Would recommend staying here. Great size for my partner, nearly 2 year old and myself. Melvin provided a travel cot and a mattress for the travel cot which was a bonus as previous air b&bs we have stayed in only provided the cot so we had to use a duvet as a make shift mattress.
One suggestion, it would be helpful to have a dust pan and brush in the apartment. With us having a young child there were crumbs from sandwiches and crisps but had no way to sweep them up.
Overall if we were to return to Madrid we would stay here again.
Thank you Melvin!
