Elza's apartment was really nice, was beautifully decorated and we felt very comfortable and homey. The kitchen is well equipped if you want to cook and the washing machine worked fine as well. The bathroom was really nice decorated and the shower is nice and big - everything was clean!
The communication with Elza was easy as well as quick - very uncomplicated! Just like the check-in since pictures were provided which definitely helped finding the entrance! :)
Location of the apartment was great too, the walk into the city is okay. Supermarkets are all around and a bus stop is also just across the road. There is also a shop where you can buy day tickets very easily.
I would definitely recommend staying with Elza if you're in Riga for a few days!
