This apartment is incredibly convenient, located literally right outside the Spagna metro station and a tiny walk around the corner from the Spanish Steps.
It is a very busy thoroughfare but once inside the apartment you don't hear much noise.
The apartment is a perfect 2 bedroom, the bedrooms and bathrooms and kitchen are all modern, very well lit, very clean, with a European washer/dryer combo unit in one of the bathrooms. Air conditioning works very well and the AC is also nearly silent.
We arrived late in the evening because of flight delays and we were able to keep in touch on WhatsApp and still met the person to let us into the apartment without any problems.
(If you are renting a car, book FAR in advance! Especially if you need an automatic transmission. With better planning we could have picked up a car at the Villa Borghese city rental location which is right through the subway tunnel, walkable from this apartment, but we waited last minute and had to get one from the train station instead which is a nightmare to do. Regardless...parking at the Villa Borghese underground garage is highly convenient and thanks again Sebastian for the recommendation!)
The windows face inner courtyards so there is limited light but still enough daylight, the apartment is not dark at all, and probably a lucky arrangement to avoid street noise. There is one flight of stairs to get to the apartment.
Very convenient home base for a few days.
