I am scheduled to land in Madrid at 12:05 PM on Tuesday, April 9th. After dropping off my luggage near the Anton Martin Metro station (not far from Atocha), I'll be looking for an interesting neighborhood to walk around in. I've walked the area from Atocha to the Plaza Mayor and over near the Palacio Real several times, and I did the Botanical Garden on jetlag day in 2016, so I'm looking for somewhere different this time.
These neighborhoods have been suggested in other threads on the forum:
Chamberi
Chueca
La Latina
Lavapies
Malasana
Any preferences among those (or other) options? My major interest in this situation will be interesting (and preferably varied) architecture, but considering I'll be a walking zombie, I may not know the difference. I won't care whether the area is lively, crowded and touristy. It wouldn't be a good time for me to tackle a marginal neighborhood, but I don't know that such even exists. I'm a big-city resident, but I am only marginally functional on arrival day.
I may also be free until 1:30 PM or so on Wednesday; I'm still trying to decide whether I dare take the 3:30 PM bus (from Estacion Sur) to Ubeda and risk a problem with my early-closing hotel if the bus is delayed. So I might have time for a second neighborhood if I don't discover an interesting exhibition at one of the museums. I hit the big 3, the Palacio Real, the Monasterio de las Descalzas Reales, and the Templo de Debod last time.
Thanks for your ideas.
