We had a very pleasant stay at Natalia's. It's an old house but very well kept. It gives you a feeling of home. Everything was sparkling clean and Natalia herself is very forthcoming.
Location is great, too. A few minutes to the train station and then just 15 minutes downtown.
Only downside: there's only bathroom and toilet for 4 rooms. There's a schedule and if everyone adheres to it, that's no big issue. But nevertheless, a second restroom or at least a toilet would've been practical.
All in all we've very much enjoyed our stay and would highly recommend this place.
