The location of Linda's flat cannot be oversold: it is smack in the middle of Old Town Riga, with less than 10 minutes walking to nearly every single sight, attraction, bar, cafe, and restaurant that we had picked out ahead of our visit. The energy of the area is unbelievable (and yes, there will be some late evening noise as a result).
The parking was a blessing -- we had rented a car in Estonia to travel nearby countries, and we were extremely worried about finding a place to park during our Riga visit. No issues there whatsoever.
The bathroom was probably the nicest part of the flat, though it was overall excellent. The shower alone is worth the price of admission!
We will definitely visit Riga again, and we would happily stay at Linda's flat when we do.
