Nice place. Quiet street but close to everything. The neighbors could be heard through the walls at times (late in the evening - use earplugs if you are a light sleeper).
Walk everywhere! We did use the metro a couple of times - easy to navigate and close by
Some people mentioned difficulty with the key, but we had no issues. Others mentioned the bed was firm, but I found it comfortable and slept well.
Adela order us a taxi to and from the airport. After a long flight, this was great. I highly recommend doing this - worth the money.
