A very nice place to stay in Madrid, very quiet and spacious. Extremely helpful host who was present to check us in early, help with the baggage, offer recommendations and generally make us feel very welcome. There were drinks left for us as well as small snacks which were so appreciated, especially the milk for our grandchildren, as there was a shortage of milk everywhere in Spain at this time. The patio was lovely but frigid temperatures made it unavailable. The internet was spotty and limited as in other Airbnb's in Spain, although the signal was better in the bedrooms.
The only downside, as mentioned in other reviews, were the four flights of stairs, which were mitigated by Javier's help with luggage. However, it was challenging with full days of sightseeing with children to confront the stairs several times a day, especially with a stroller.
