Book early for summer (Jun-Aug) — Riga's hotel supply is limited and the best Old Town properties sell out weeks in advance during peak season.
Consider apartments for 3+ nights — Riga has excellent serviced apartments, especially in the Quiet Centre, often at half the price of equivalent hotel rooms.
Airport transfers are cheap — A taxi from Riga Airport to Old Town costs €10-15 and takes 15 minutes. The airport bus (Bus 22) costs €2 and takes 30 minutes.
Free cancellation is standard — Most Riga hotels on Booking.com offer free cancellation up to 24-48 hours before check-in, so book early and adjust later.
