Walter's place is the best BnB we've stayed in. Everything in the apartment is new and comfortable.
The kitchen was well equipped and provisioned and the additional benefit of a big private rooftop terrace overlooking the plaza was great. Breakfast was included at the cafe below the apartment and parking was provided at a nearby garage.
The apartment is on the first floor but unlike most places, there is an elevator which makes it easy to manage baggage.
I highly recommend Walter's place and would give it more stars if I could.
