Spent 4 nights in the apartment. Nice place, very clean with everything you need, in a perfect location for exploring the Old Town. 5 mins from a lot of tourist sites & museums. Also found it was within walking distance to other parts of the city as Riga is quite compact. Was very quick & easy to get a Bolt too. Apartment had everything you need & shower + heated floor were really nice too. All at a great price.
Martin was also super helpful and sent us some tourist information and clear info around check in/out.
Although there was no where in the apartment block to store bags before check in / after check out (as our flights didn't line up with check in/out times), Martin sent us over an app which had locations in the Old Town where you could book in and store your luggage for the day, which whilst a little less convenient than having something in the building, was fine (we stored ours in a Hostel near by).
Overall had a great experience and would deffo recommend!
