Madrid, Spain and Lisbon, Portugal

If you have the time, also try to get out to El Escorial from Madrid for a half-day visit. It’s a short commuter train ride from Atocha station…about one hour.

Thanks for the fast response. Traveling by train can be hard because I use an electric scooter and boarding and debarking becomes a challenge, to say the least. I will have to see what is entailed when I get there. Buses usually work, I use the work usually. Sometimes, the pole in the center of the isle is a real challenge, as is boarding a bus without a ramp.

For some that might not be enough but for me personally that is plenty of time for not just Madrid but to also do trips outside the city. When we were there last year, we did Toledo and Segovia as day trips outside Madrid. For Lisbon, we did Fatima as an overnight trip (that was a special intention) and Sintra for a day trip.
For Toledo, take the Avant train from Atocha Renfe station (purchase in advance because it sells out easily). There are free maps near Plaza de Zocober for a DIY tour of the city. For Segovia (can be purchased same day of departure) take the train from Chamartin Renfe station. For Sintra (from Lisbon) take the CP train from Rossio (can be purchased same day of dep).
These are great cities to visit at least once in your lifetime but make the most of your time!

I would say each if you can do daytrips, one week in each city is great. From Madrid you have Toledo, Segovia, El Escorial. Even if you cannot make it out of town, Madrid is a great art City, you have the Plaza Mayor, Plaza Santa Ana, Calle De Huertas pedestrian zone. The Thiessen Musuem is great, too, and the Parque de Buen Retiro especially on weekends when the locals go strolling. Lisbon is hilly, sometimes the pavement is uneven so a little more challenging but could be done. Sintra is magical as a daytrip from Lisbon. It too is hilly but so rewarding. Lisbon has the Gulbinkian museum, a really great art museum. Belem is a lot of fun too.
