Good: All the amenities required (Fridge, mini kitchen, coffee machine, etc.) and clean apartment. Aircon in all the rooms. Walking distance to public transport and key sights. Great service when we checked in. We could store our luggage and Alvaro was kind enough to carry our bags into our room as we got back only after 6pm.
To be considered before booking: Our room was on the 5th floor, with no lift and narrow staircase. Not ideal if you cannot walk 100+ steps up and down or if you have a lot of luggage. Also, the noise from the other apartments was very loud. If you only use the two bedrooms, you are at least able to close the door, but if you use the couch bed then you are literally a meter away from the main door and exposed to the noise. Also, be very clear about what time you could leave luggage for storage, as the office was closed when we checked out (even though it was during their official opening hours).
