Ramon's place was great for our stay in Madrid. Check-in was extremely smooth thanks to Marco, Ramon's friend. When we arrived to Madrid around 11:30am, we met Marco at the Airbnb and he was able to let us into the apartment earlier than expected to store our luggage while we go sight-seeing.
There was also plenty of space for the four of us and having two bathrooms was super convenient for getting ready in the morning. The place was clean and towels were provided for each person. There were no other toiletries provided though, but we brought our own. Location-wise, Ramon's place is close to mostly everything we wanted to see. It was a 5 minute walk away from Plaza de Santa Ana, shopping, and public transit (the Sol metro and the Anton Martin station). We were able to see all the other sights through public transit and the area was safe at night, except for the occasional club/bar promoter but they're harmless.
Overall we enjoyed our stay and would stay again!
