Fernando's place is in an awesome location. We didn't use the metro the whole four days we visited because everything was within a 25minute walk. Checkin was a little unclear, but we called when we got there and Fernando was able to have someone open the door for us within 10 minutes. We had one other hiccup where the hot water stopped working and all the controls were in the sister unit, so we went one day with no hot water. However, Fernando was quick to fix the problem the next morning and give us some credit for that night. You can hear neighbors walking up the stairs or entering the sister unit, but it wasn't awful. The bed was quite firm but we found it comfortable and the place had all the necessary amenities. We really appreciated how Fernando and Luis let us leave our bags in the room post-checkout since our flight was later.
