I stayed at Maribels place for four weeks. It is a great small studio with many thoughtful touches. Lots of light, and la terraza (walk-out roof deck) was may absolutely favorite place for having breakfast. Proximity to Alameda de Hercules is very nice, because it is a center for evening activities for young and olds. Market is 5 minute to walk, a nice grocery store 2 mins.
Maribel is extremely kind and thoughtful host, and believe me I seen many airbnb places in number of countries. Highly recommend this place for a short or long stay.
